Embodiment 1

[0130] 162.2 g of propylene glycol monomethyl ether acetate was placed in a flask equipped with a stirring device, a dropping funnel, a condenser, a thermometer, and a gas introduction tube, and the temperature was raised to 120° C. while stirring while replacing nitrogen.

[0131] Next, methacryloyloxyethyl isocyanate represented by 4.7g (0.05 mol) of norbornene, 53.0g (0.45 mol) of vinyltoluene, 32.4g (0.45 mol) of acrylic acid and the above-mentioned formula (3) and 10.3 g of tert-butylperoxy-2-ethylhexanoate (polymerization initiator, Japanese Oil Co., Ltd. (Parbull O), and the obtained solution was dropped into the above-mentioned flask from the dropping funnel over 2 hours. After completion|finish of dripping, it stirred at 120 degreeC for 2 hours, and copolymerization reaction was performed, and the addition copolymer (precursor of curable polymer) was produced|generated. Then, the inside of the flask was replaced with air, 22.5 g (0.16 mol) of glycidyl methacrylate, 0...

Embodiment 2

[0134] 232.8 g of propylene glycol monomethyl ether acetate was added to a flask equipped with a stirring device, a dropping funnel, a condenser, a thermometer, and a gas introduction tube, and the temperature was raised to 120° C. while stirring while replacing nitrogen. Next, in 6.09g (0.06 mole) of norbornene, 68.33g (0.58 mole) of vinyltoluene, 82.0g (0.58 mole) of glycidyl methacrylate and the methacryloyl oxide represented by the above formula (3) 13.3 g of tert-butyl peroxy-2-ethylhexanoate ( Polymerization initiator, manufactured by NOF Corporation, Perbucell (2), and the obtained solution was dropped into 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. Then, the inside of the flask was replaced with air, and 42.0 g (0.58 mol) of acrylic acid, 0.5 g of triphenylphosphine (catalyst) a...

Embodiment 3

[0137] Use 13.4 g (0.05 mol) of the reaction product (dissociation temperature 160°C) of 2-isocyanatoethyl methacrylate represented by the above formula (2) and ε-caprolactam instead of the methyl group represented by the above formula (3) A polymerizable polymer (C) was obtained in the same manner as in Example 1 except that the reaction product of acryloyloxyethyl isocyanate and propylene glycol monomethyl ether was 12.25 g (0.05 mol). The acid value of the polymer was 130.2 mgKOH / g, the unsaturated group equivalent was 859 g / mol, the blocked isocyanate group equivalent was 2700 g / mol, and the weight average molecular weight was 15900.

[0138] Next, 106.53 g of propylene glycol monomethyl ether was added to the reaction solution to prepare a polymer solution in which the concentration of the polymer portion of the polymerizable polymer (C) was 34%. Let this be sample 3.

Abstract

Provided is a curable polymer that contains an acid group, a polymerizable unsaturated group and a blocked <span lang=EN style='font-family:"Courier New"'>isocyanato group. The curable polymer<span lang=EN style='font-family:"Courier New"'> has a weight average molecular weight of 1,000 to 50,000 in terms of polystyrene, and preferably has an acid value of 20 to 300 mg KOH / g, an unsaturated group equivalent of 100 to 4,000 g / mol, and a blocked isocyanato group equivalent of 400 to 6,000 g / mol. After mixing the curable polymer with a solvent, blending in a reactive diluent, a photopolymerization initiator and a colorant to prepare a photosensitive material for a color filter, and using said photosensitive material to form a pattern, a color filter is obtained by preferably baking said pattern at 210°C or less.

Description

technical field [0001] The present invention relates to a novel curable polymer containing blocked isocyanate groups and uses thereof, more specifically, to a curable polymer suitable as a photosensitive material for color filters, a polymer containing the curable polymer composition, a photosensitive polymer composition containing a photopolymerization initiator in the polymer composition, a color filter formed from the photosensitive polymer composition, a method for producing the color filter, and a photosensitive polymer composition comprising the photosensitive polymer composition Color filter image display element. Background technique [0002] In recent years, photosensitive polymer compositions curable by active energy rays such as ultraviolet rays or electron beams have been widely used in the fields of various coatings, printing, paints, adhesives, etc. from the viewpoint of saving resources and energy. In addition, in the field of electronic materials such as pri...
