<p>PURPOSE:To provide the subject material containing an unsaturated compound, a photo-initiator and a compound produced by reacting a polybasic carboxylic acid with a reaction product of a specific epoxy compound and (meth)acrylic acid, capable of forming a fine pattern and resistant to the generation of color and crease. CONSTITUTION:The objective material for a color filter can be produced by compounding (A) a carboxylic acid compound containing unsaturated group and produced by reacting an epoxy compound of formula with (meth)acrylic acid and further reacting the reactional product with a polybasic carboxylic acid or its anhydride (e.g. tetrahydrophthalic anhydride), (B) a compound containing ethylenic unsaturated group other than the component A (e.g. phenoxyethyl methacrylate) and (C) a photo-polymerization initiator (e.g. benzoin). The material is coated on a glass plate by spin-coating, dried at 70 deg.C for 10min, masked with a negative film placed in a state separated from the coating film, irradiated with ultraviolet ray and treated with 1% aqueous solution of sodium carbonate to dissolve and remove the non-irradiated part of the coating film and obtain a cured product having high resolution.</p> |
