    摘要： A colored photosensitive composition is provided to improve the balance of sensitivity and solubility and to enhance of the sharpness of pixel edge and adhesion. A colored photosensitive composition comprises a photopolymerizable compound comprising a resin obtained by reacting a reaction product of an epoxy compound and an ethylenically unsaturated carboxylic acid compound with a polybasic acid anhydride; a photopolymerization initiator; and a colorant, wherein the epoxy compound comprises an epoxy compound having a biphenyl structure and an epoxy compound having a cardo structure.

    摘要： PROBLEM TO BE SOLVED: To provide a photosensitive resin composition which allows formation of a spacer having a high breaking strength, a good shape, and good adhesion to a substrate, and to provide a liquid crystal panel having the spacer formed of the photosensitive resin composition. SOLUTION: The photosensitive resin composition contains an alkali-soluble resin (A), a photopolymerizable monomer (B), and a photoinitiator (C). The alkali-soluble resin (A) contains: an alkali-soluble resin (A1) having a structural unit (a1) derived from an unsaturated carboxylic acid and a structural unit (a2) derived from an epoxy group-containing unsaturated compound; and an alkali-soluble resin (A2) having the structural unit (a1) and a structural unit (a3) having a portion polymerizable with the photopolymerizable monomer (B); or an alkali-soluble resin (A3) having structural units (a1), (a2), and (a3). A ratio of the structural unit (a2) to each of alkali-soluble resins (A1) and (A3) is ≥71 mass%. COPYRIGHT: (C)2011,JPO&INPIT

    摘要： This invention is to provide a photosensitive composition having higher sensitivity. The photosensitive composition comprises a photo-polymerizable compound and a photo-polymerization initiator, wherein the photo-polymerization initiator has a skeleton which can be represented by formula (1) and a light absorbance rate higher than 0.3 at the wavelength of 365 nm. In formula (1), A, B and G are monovalent organic groups, and E is a substituted conjugated ring.
