[0150]

[0151] Hereinafter, the present specification will be described in more detail.

[0152] One embodiment of the present invention provides a positive photosensitive resin composition comprising: an alkali-soluble polymer resin; an esterified quinonediazide-based compound; and a crosslinking agent including a phenol group; wherein the alkali-soluble polymer resin comprises a reaction product of a mixture including an amine-based compound, an acid anhydride-based compound, and a capping compound, and satisfies the following formula 1:

[0153] [Formula 1]

[0154] (A+B) / 2 < 6.0 eV

[0155] In the above formula 1, A is the CTC value (eV) of the amine compound, B is the sum of the CTC value (eV) of the acid anhydride compound and the CTC value (eV) of the capping compound in a mixture of the acid anhydride compound and the capping compound, and the CTC value means a quantum calculation simulation value for the energy level difference between the electron donor and electron acceptor of the compound, assuming that the compound forms a charge transfer complex.

[0156] A positive photosensitive resin composition according to one embodiment of the present invention may have excellent sensitivity, film retention, adhesive strength, chemical resistance, heat resistance, solar resistance, hygroscopicity, operating reliability, and bending characteristics.

[0157] According to one embodiment of the present invention, the alkali-soluble polymer resin satisfies the above formula 1. Specifically, the CTC value of the alkali-soluble polymer resin calculated by the following formula 1-1 may be 3.5 eV or more and less than 6.0 ev.

[0158] [Formula 1-1]

[0159] CTC(ev) of alkali-soluble polymer resin = (A+B) / 2

[0160] In the above equation 1-1, A and B are the same as defined in the above equation 1. At this time, the CTC value means a quantum calculation simulation value for the energy level difference between the electron donor (HOMO) and electron acceptor (LUMO) of each of the amine compound, acid anhydride compound, or capping compound, assuming that each of the amine compound, acid anhydride compound, or capping compound forms a charge transfer complex. At this time, the quantum calculation simulation value can be calculated through M06-2X / 6-311G by applying Gaussian 16, Density Functional Theory.

[0161] According to one embodiment of the present invention, the CTC value of the amine compound may be a CTC value based on 100 parts by weight of the amine compound. For example, based on 100 parts by weight of the amine compound represented by Compound 1-2 described below, the CTC value of Compound 1-2 may be 4.56 ev. In addition, based on 100 parts by weight of the amine compound represented by Compound 1-15 described below, the CTC value of Compound 1-15 may be 5.49 ev. Meanwhile, the amine compound may include one or more amine compounds. At this time, the CTC value of the amine compound may be calculated through the CTC value of each of the amine compounds included in the amine compound and the weight ratio (mixing ratio) of the amine compounds. For example, based on 100 parts by weight of the amine compound, the content of Compound 1-2 may be 30 parts by weight and the content of Compound 1-15 may be 70 parts by weight. At this time, the CTC value (A) of the amine compound in the above formula 1 and formula 1-1 may be the sum of the CTC value of compound 1-2 (4.56 ev X (30 / 100)) and the CTC value of compound 1-15 (5.49 ev X (70 / 100)) in the amine compound.

[0162] According to one embodiment of the present invention, the CTC value of the acid anhydride compound may be a CTC value based on 100 parts by weight of the acid anhydride compound. In this case, 100 parts by weight of the acid anhydride compound may be a content based on 100 parts by weight of the amine compound. For example, based on 100 parts by weight of the acid anhydride compound represented by Compound 2-4 described below, the CTC value of Compound 2-4 may be 5.92 ev. In addition, the CTC value of the capping compound may be a CTC value based on 100 parts by weight of the capping compound. In this case, 100 parts by weight of the capping compound may be a content based on 100 parts by weight of the amine compound. For example, based on 100 parts by weight of the capping compound represented by Compound C-4 described below, the CTC value of Compound C-4 may be 4.60 ev.

[0163] In the above formula 1 and formula 1-1, the sum (B) of the CTC value (eV) of the acid anhydride compound and the CTC value (eV) of the capping compound can be calculated as follows. For example, based on 100 parts by weight of the amine compound, the content of compound 2-4 can be 80 parts by weight and the content of compound C-4 can be 40 parts by weight. In the above formula 1 and formula 1-1, B can be the sum of the CTC value of compound 2-4 (5.92 ev X (80 / 120)) and the CTC value of compound C-4 (4.60 ev X (40 / 120)) in the mixture of the acid anhydride compound and the capping compound.

[0164] According to one embodiment of the present invention, the CTC value of the alkali-soluble polymer resin calculated by the above formula 1-1 is 3.5 eV or more and less than 6.0 ev, 3.7 eV or more and 5.99 ev or less, 3.9 eV or more and 5.95 ev or less, 4.0 eV or more and 5.9 ev or less, 4.2 eV or more and 5.8 ev or less, 4.4 eV or more and 5.7 ev or less, 4.6 eV or more and 5.6 ev or less, 4.8 eV or more and 5.5 ev or less, 5.0 eV or more and 5.4 ev or less, 4.0 eV or more and 5.5 ev or less, 4.3 eV or more and 5.2 ev or less, 4.6 eV or more and 5.1 ev or less, 4.7 eV or more and 5.0 ev or less, 5.0 eV or more and 5.99 ev or less, 5.2 It can be 5.95 eV or more and 5.4 eV or more and 5.9 eV or less, or 5.6 eV or more and 5.8 eV or less.

[0510] Synthesis of alkali-soluble polymer resins

[0511] For the above combination of diamine compounds (total diamine compounds), an acid anhydride compound and a capping compound were reacted as follows to produce an alkali-soluble polymer resin. In the tables below, the content of the acid anhydride compound and the content of the capping compound (parts by weight) are based on 100 parts by weight of the combination of diamine compounds (total diamine compounds).

[0512] Specifically, the above-described amine compound (a combination of diamine compounds) was added to gamma-butyrolactone and dissolved at 90°C. Thereafter, an acid anhydride compound was added according to the following recipe and stirred at 105°C for 4 hours. Thereafter, a capping compound was added according to the following recipe and reacted at 70°C for 2 hours, and then the temperature was raised to 150°C. Thereafter, water generated by the reaction was removed using a Dean-Stark extractor, and the reaction was terminated after stirring at 180°C for 4 hours, thereby synthesizing an alkali-soluble polymer resin.

[0527] Physical property analysis of alkali-soluble polymer resins

[0528] The CTC value (ev) and imidization degree of the alkali-soluble polymer resins manufactured in the above synthetic examples and comparative synthetic examples were calculated and shown in the tables below.

[0529] In Tables 21 to 24 below, the CTC calculation values ​​are derived using the above formula 1-1.

[0530] [Formula 1-1]

[0531] CTC(ev) of alkali-soluble polymer resin = (A+B) / 2

[0532] In addition, in Tables 21 to 24 below, the degree of imidization means the content of the repeating unit represented by the chemical formula B based on 100 mol% of the total of the repeating unit represented by the chemical formula A and the repeating unit represented by the chemical formula B in the alkali-soluble polymer resin.

[0533] At this time, the mol% of the repeating unit contained in the alkali-soluble polymer resin can be calculated by confirming the conversion rate through comparison of the -CNC- peak of the imide bond in the FT-IR measurement results. Specifically, the alkali-soluble polymer resin was coated on a glass surface, and heated at a temperature of 120 °C for 120 seconds to obtain a sample (a). In addition, the alkali-soluble polymer resin was coated on a glass surface, and heated at a temperature of 120 °C for 120 seconds, and then heated at a temperature of 350 °C for 60 minutes to obtain a sample (b).

[0534] FT-IR measurements are performed on the obtained samples (a) and (b). At this time, C=C (Aromatic, 1510 cm -1 ), CNC(1370 cm -1 ) was measured. Afterwards, the degree of imidization (CNC / C=C) was compared to calculate the molar % (degree of imidization) of the repeating unit represented by chemical formula B.

[0569]

[0570] Experimental example

[0571] For the positive photosensitive resin compositions manufactured in the above examples and comparative examples, the fluorine content, sensitivity, film retention rate, adhesive strength, chemical resistance, heat resistance, solar resistance, hygroscopicity, operating reliability, and bending characteristics were measured by the following methods. The measured results are shown in Tables 30 to 33 below.

[0572]

[0573] Fluorine content measurement

[0574] The content of fluorine contained in the photosensitive resin composition was measured using combustion ion chromatography (CIC).

[0575]

[0576] Sensitivity measurement

[0577] A substrate coated with a photosensitive resin composition was irradiated with ultraviolet rays having an intensity of 20 mW / cm2 in a broadband using a predetermined pattern mask at a standard dose for forming a 5 μm contact hole CD, and then developed with an aqueous solution of 2.38 parts by weight of tetramethylammonium hydroxide at 23°C for 1 minute and washed with ultrapure water for 1 minute. Thereafter, the film was cured in an oven at 250°C for 60 minutes to obtain a pattern film having a contact hole CD of 7 μm. The sensitivity was 40 to 150 mJ / cm. 2 If this is satisfied with the appropriate result value, it is marked as O.

[0578]

[0579] Measurement of residual film ratio

[0580] The residual film ratio of the above-mentioned manufactured substrate was measured by comparing the initial coating thickness and the final thickness after all processes were performed. If the ratio of the final thickness to the initial thickness was 60% or more, it was marked as O, and if it was less than 60%, it was marked as X.

[0581]

[0582] Adhesion measurement

[0583] A pattern film was formed in the same manner as in the sensitivity measurement above, but the adhesive strength according to the baking temperature was compared based on a case where the line width and slit width were 10 ㎛ and 1:1. At this time, a case where the adhesive strength was secured at a prebake of 90 ℃ to 100 ℃ was marked as O, and a case where the adhesive strength was secured at a prebake of 120 ℃ or higher or not was marked as X.

[0584]

[0585] Chemical resistance measurement

[0586] The above-mentioned manufactured substrate was immersed in an evaluation solvent (Stripper) at 25°C for 120 seconds, and the change rate of the cured film thickness before and after immersion was measured. 0 Å or more and less than 150 Å was marked as ◎, 150 Å or more and less than 300 Å was marked as ○, 300 Å or more and less than 600 Å was marked as △, and 600 Å or more was marked as X (evaluation solvent was propylene glycol methyl ether: propylene glycol methyl ether acetate = 7:3 molar ratio).

[0587]

[0588] Heat resistance measurement

[0589] For the above sensitivity evaluation, the organic film portion of the manufactured substrate (up to the curing process completion) was recovered and evaluated using a TGA (Thermogravimetric Analyzer) at 50 to 500°C, 10°C / min. If the standard temperature for weight loss (5% of weight loss) was 350°C or higher, it was marked as ◎, if it was 300°C or higher but less than 350°C, it was marked as ○, and if it was less than 300°C, it was marked as X.

[0590]

[0591] Solar resistance measurement

[0592] In the same way as the sensitivity measurement above, a pattern film is formed on a patterned ITO substrate, and EL is deposited. Al is deposited on top as a cathode electrode, and an encapsulation process is performed. After irradiating 2100 J of exposure dose 10 times using a xenon lamp solar simulator, the time (T97) for a 3% luminance drop in the on state is evaluated. If it is secured for 1000 hours or more, it is marked with ○, and if it is secured for less than 1000 hours, it is marked with X.

[0593]

[0594] Hygroscopicity measurement

[0595] For the above sensitivity evaluation, the manufactured substrate was purified in a constant temperature and humidity oven at 85°C and 85% RH for 240 hours, and then the hygroscopicity was evaluated based on the change in film thickness before and after being placed in the oven. If the thickness change rate was less than 300 Å, it was marked as ◎, if it was 300 Å or more but less than 600 Å, it was marked as ○, and if it was 600 Å or more, it was marked as X.

[0596]

[0597] Drive reliability measurement

[0598] A pattern film can be formed using the same method as in the above sensitivity measurement.

[0599] Fig. 1 is a drawing showing forming a pattern film on an ITO substrate on which a pattern has been formed and depositing EL. Specifically, 10 in Fig. 1 represents a source / drain (Ti / Al / Ti), 20 represents an organic film, 30 represents an anode (ITO / Ag / ITO), and 40 represents a pixel define layer (PDL).

[0600] As shown in Fig. 1, Al is deposited as a cathode on the upper side, and an encapsulation process is performed. The time (T97) for a 3% luminance drop in the device ON state at 85 ℃ and 85% RH was evaluated. If it is secured for 1000 hours or more, it is marked with ◎, if it is less than 1000 hours but more than 950 hours, it is marked with ○, and if it is less than 950 hours, it is marked with X.

[0601]

[0602] Measurement of bending characteristics

[0603] A 100 ㎛ thick polyimide (PI) film was coated with a material in a thickness of 3 ㎛ and folded 200,000 times with a radius of curvature of 1R. If numerous cracks were observed in the folding portion, it was marked as X, and if no cracks were observed, it was marked as O.

[0614] On the other hand, in the case of Comparative Examples 1 to 26, it was confirmed that the physical properties were inferior to those of Examples 1 to 124. Specifically, in the case of the positive photosensitive resin compositions of Comparative Examples 1 to 26, it was confirmed that the chemical resistance, heat resistance, solar resistance, hygroscopicity, operating reliability, and bending characteristics were very inferior.

[0615] Therefore, it can be seen that the positive photosensitive resin composition according to one embodiment of the present invention can easily implement an organic film having excellent sensitivity, film retention rate, adhesive strength, chemical resistance, heat resistance, solar resistance, hygroscopicity, operating reliability, and bending characteristics.
