Embodiment 1

[0033] This example illustrates the film-forming resin and the thermosetting resin composition containing the film-forming resin provided by the present invention.

[0034] The glycidyl methacrylate of 80 parts by weight, the benzyl methacrylate of 20 parts by weight, the azobisisobutyronitrile of 2.5 parts by weight, the propylene glycol methyl ether acetate of 50 parts by weight and the ethylene glycol of 50 parts by weight Monobutyl ether acetate mixes homogeneously, obtains mixed solution, this mixed solution is placed in dropping funnel, and control flow rate is 0.5 milliliters / minute, under nitrogen atmosphere, this mixed solution is added dropwise to 20 parts by weight of propylene glycol methyl ether acetic acid In a mixed solvent of the ester and 20 parts by weight of ethylene glycol monobutyl ether acetate, the temperature of the mixed solvent is 80° C. to obtain a film-forming resin solution. In the preparation reaction of the film-forming resin described in the pre...

Embodiment 2

[0043] The film-forming resin was prepared according to the method of Example 1, except that the curing agent also contained 35 parts by weight of 1-methoxy-1-ethoxyethane. In the obtained film-forming resin, the molar ratio of units formed from glycidyl methacrylate to units formed from benzyl methacrylate is 1-5:1. The obtained film-forming resin had a weight average molecular weight of 21,000. Finally, a thermosetting resin composition solution A2 with a solution viscosity of 9 mPa·s was obtained.

Embodiment 3

[0045] This example illustrates the film-forming resin provided by the present invention and the thermosetting resin composition using the film-forming resin.

[0046] 70 parts by weight of glycidyl-α-ethyl methacrylate, 30 parts by weight of phenylethyl methacrylate, 2.5 parts by weight of azobisisobutyronitrile, 60 parts by weight of dimethyl glutarate and 40 parts by weight The ethylene glycol monobutyl ether acetate of weight part is mixed homogeneously, obtains mixed solution, this mixed solution is placed in dropping funnel, control flow velocity is 1 milliliter / minute, under nitrogen atmosphere, this mixed solution is added dropwise to 15 wt. In a mixed solvent of dimethyl glutarate and 10 parts by weight of ethylene glycol monobutyl ether acetate, the temperature of the mixed solvent is 80° C. to obtain a film-forming resin solution. In the film-forming resin, the molar ratio of units formed from glycidyl-α-ethyl methacrylate to units formed from phenethyl methacrylate...

Abstract

The invention provides a film forming resin which comprises a unit formed by a monomer A and a unit formed by a monomer B, wherein, the monomer A is the methyl acrylate with an epoxide group, the monomer B is one or more than one of the (methyl) benzyl acrylate, the (methyl) acrylic acid phenethyl ester and the (methyl) acrylic acid phenyl ester, in the film forming resin, the mol ratio of the unit formed by the monomer A and the unit formed by the monomer B is between 1:1 and 8:1, the weight average molar mass of the film forming resin is between 5000 and 100000. The thermocuring resin compound greatly improves the hardness of a protective film for a colorful spectral filter and the heat-resistant polychromasia. In addition, the thermocuring resin compound has good storage stability; the protective film formed by the thermocuring resin compound has good heat resistance, leveling property, light-admitting quality, anti-ITO sputtering property, etching-proof characteristic, adhesive attraction and the uniformity of the film thickness.

Description

technical field [0001] The present invention relates to a film-forming resin and a thermosetting resin composition containing the film-forming resin, in particular to a film-forming resin used for a color filter protective film and a thermosetting resin composition containing the film-forming resin things. Background technique [0002] In recent years, thin film transistor liquid crystal display (TFT-LCD) is the fastest growing flat panel display device and is expected to become the mainstream of the display market. The color filter for TFT-LCD includes glass substrate, black matrix (Black matrix), color filter layer, protective film and transparent electrode layer (such as ITO layer), this color filter is passed on the transparent glass substrate Make an anti-reflective light-shielding layer-black matrix, and then make a color filter layer with light-transmitting red, green, and blue primary colors in turn, and then coat a protective film (Over Coat) on the color filter la...
