Problems solved by technology

However, this material exhibits excellent characteristics in terms of sensitivity, developability, thermal decomposition resistance, and thermal yellowing resistance, but the adhesion to the substrate or the flexibility of the coating film is not necessarily sufficient. In addition, dyes are used as coloring materials When it is used, it often causes the phenomenon that the original brightness of the dye is insufficient.

Embodiment 1

[0148] Into a flask equipped with a stirring device, a dropping funnel, a condenser, a thermometer, and a gas introduction tube, 262.0 g of propylene glycol monomethyl ether acetate was charged, stirred while nitrogen substitution was performed, and the temperature was raised to 120°C.

[0149] Next, 49.7 g (0.27 moles) of 2-ethylhexyl acrylate, 99.4 g (0.7 moles) of glycidyl methacrylate, and 2-ethylhexyl acrylate with a glass transition temperature of -70°C when forming a homopolymer, and To a monomer mixture of 6.6 g (0.03 mol) of cyclopentyl ester, 19.0 g of tert-butyl peroxy-2-ethylhexanoate (polymerization initiator, manufactured by NOF Corporation, Parbull O) was added, and the obtained substance It was added dropwise to the above-mentioned flask from the dropping funnel over 2 hours. After completion of the dropwise addition, the mixture was further stirred at 120° C. for 2 hours to perform a copolymerization reaction to produce an addition copolymer (precursor of a cu...

Embodiment 2

[0152] In place of 2-ethylhexyl acrylate, 130.1 g (0.27 mol) of methoxypolyethylene glycol acrylate (AM-90G manufactured by Shin-Nakamura Chemical Industry Co., Ltd.) with a glass transition temperature of -71°C when forming a homopolymer was used 49.7 g (0.27 mol) and 19.0 g of tert-butyl peroxy-2-ethylhexanoate were changed to 28.8 g, and the curable polymer (B) was obtained like Example 1. The Tg of the polymer is -9°C, the acid value is 23KOHmg / g, the unsaturated group equivalent is 480g / mol, and the weight average molecular weight is 8700. In addition, the hydroxyl value was 93KOHmg / g. Next, propylene glycol monomethyl ether was added to the reaction solution to prepare a polymer solution having a solid content concentration of the curable polymer (B) of 40%. Let this be sample 2.

Embodiment 3

[0154]In addition to using 94.0 g (0.37 moles) of m-phenoxybenzyl methacrylate with a glass transition temperature of -35 °C when forming a homopolymer instead of 49.7 g (0.27 moles) of 2-ethylhexyl acrylate, and adding 99.4 g (0.7 mol) of glycidyl acrylate was changed to 85.2 g (0.6 mol), tert-butyl peroxy-2-ethylhexanoate was changed to 22.7 g, 50.4 g (0.7 mol) of acrylic acid was changed to 43.2 g Except that (0.6 mol), the curable polymer (C) was obtained in the same manner as in Example 1. The Tg of the polymer is -8°C, the acid value is 29KOHmg / g, the unsaturated group equivalent is 460g / mol, and the weight average molecular weight is 7200. In addition, the hydroxyl value was 94KOHmg / g. Next, propylene glycol monomethyl ether was added to the reaction solution to prepare a polymer solution having a solid content concentration of the curable polymer (B) of 40%. Let this be sample 3.

Abstract

The invention provides a cured polymer which is characterized in that a side chain obtained by modifying an addition multipolymer contains acidyl, hydroxyl and polymerized unsaturated bonds, Tg being below 20 DEG C and the weight-average molecular weight of polystyrene conversion being 1000-50000. The addition multipolymer contains 5-40 mol% of a (meth)acrylate monomer (a) whose glass-transition temperature (Tg) is below 10 DEG C after formation of a homopolymer, 30-85 mol% of a (meth)acrylic acid-based monomer (b) containing epoxy groups or carboxyl and 0-35mol% of other free radical polymerized monomers (c). A photosensitive polymer composition can be formed by adding a reactive diluent and a photopolymerization initiator in the cured polymer.
