Embodiment

[0157] Hereinafter, embodiments of the present invention will be described in detail based on examples, but the present invention is not limited to these examples. In addition, "part" and "%" described in this specification represent a weight part and weight% unless there is a notice in particular.

[0158] 1. Preparation of thermoplastic binder resin (B)

[0159] The measurement methods of various properties of the resin are as follows.

[0160] (hydroxyl value)

[0161] Use the excess acid anhydride to esterify or acetylate the hydroxyl group in the resin, and use the base to reverse titrate the remaining acid. The amount of hydroxyl groups in 1 g of the resin was calculated by back titration, and converted into mg of potassium hydroxide. More specifically, it is the value obtained by the measuring method based on JISK0070.

[0162] (acid value)

[0163] Calculated from the mg of potassium hydroxide required to neutralize the acid groups contained in 1 g of the resin. ...

Synthetic example 1

[0180] 120 parts of polyester diol obtained from adipic acid and 1,2-propylene glycol with a number average molecular weight of 2000, 80 parts of polypropylene glycol with a number average molecular weight of 2000, 23.3 parts of isophorone diisocyanate, and 18.3 parts of toluene diisocyanate , and 60.4 parts of ethyl acetate were reacted at 80° C. for 4 hours under a nitrogen stream to obtain a solution of a terminal isocyanate prepolymer.

[0181] Next, 23.3 parts of isophorone diamine and 550.4 parts of a mixed solvent of ethyl acetate / isopropanol=50 / 50 were mixed, and the solution of the terminal isocyanate prepolymer prepared before was slowly added to the mixture at 40° C. , and react at 80°C for 1 hour.

[0182] In this way, solid content was 30%, the amine value was 6.5 mgKOH / g, and the polyurethane-type resin solution PU1 whose weight average molecular weight was 32000 was obtained. In addition, the glass transition temperature of the polyurethane-type resin calculate...

Synthetic example 2～5

[0184] Polyurethane-based resin solutions PU2 to PU5 were obtained by the same method as in Synthesis Example 1 using the raw materials shown in Table 1.

[0185] In addition, the raw material described in Table 1 is as follows.

[0186]

[0187] Polyester polyol (b1-1-1)

[0188] PMPA: Polyester diol which is a condensate of adipic acid and 3-methyl-1,5-pentanediol, and the number average molecular weights are 5000, 2000 and 1000 respectively (P5010 manufactured by Kuraray Co., Ltd., P2010 and P1010)

[0189] PPA: polyester diol with a number average molecular weight of 2000 as a condensate of adipic acid and 1,2-propanediol

[0190] Polyether polyol (b2-1-2)

[0191] PPG: Polypropylene glycol with a number average molecular weight of 2,000 (2020 manufactured by ACG Corporation)

[0192] Other polyols

[0193] PCL: polycaprolactone diol having a number average molecular weight of 2000 obtained by ring-opening polymerization of ε-caprolactone (PCL220N manufactured by Da...

Abstract

A coating agent composition for printing which comprises resin particles (A) having a glass transition temperature in the range of -80 to -35oC and an average particle diameter in the range of 2-20 [mu]m, a thermoplastic binder resin (B), and an organic solvent (C).

Description

technical field [0001] The present invention relates to a coating agent composition for printing which can form a coating film by printing and has good texture and rub resistance of the coating film. Moreover, this invention relates to the printed matter which has the coating layer formed using the said coating agent composition for printing. Background technique [0002] Conventionally, in terms of design aspects such as solidity and luxury, it is usually used in electrical and electronic equipment-related parts such as personal computer casings, automotive interior parts such as instrument panels, center consoles, instrument panels, and door trims, The surface of plastic products used for life-related parts such as chair legs, armrests, railings, window frames, and door handles, or furniture and building materials-related parts, or the surface of paper products used for packaging boxes such as cosmetic boxes are matted with matting paint coating film. In recent years, fu...
