    摘要: A composition for a light-scattering film contains fluorine-containing resin fine particles each including a copolymer of a first ethylenically unsaturated monomer containing fluorine with other ethylenically unsaturated monomer component, and having an average particle diameter of 0.8 to 5.0 μm; and a transparent resin having a refractive index of 1.50 to 1.70. Where the other ethylenically unsaturated monomer component is formed of a second ethylenically unsaturated monomer containing no fluorine nor hydrophilic group, the copolymer contains 10 to 60% by weight of the first monomer, and 90 to 40% by weight of the second monomer. Where the other ethylenically unsaturated monomer component is formed of the second monomer and a third ethylenically unsaturated monomer containing a hydrophilic group, the copolymer contains 10 to 90% by weight of the first monomer, 89 to 5% by weight of the second monomer and 1 to 10% by weight of the third monomer.

    摘要: A photosensitive resin composition is comprised of (A) a polyimide resin having a weight-average molecular weight of from 5,000 to 150,000, represented by the general formula (I): ##STR1## wherein X is a specified tetravalent organic group having two benzene rings, Y is a member comprised of 30-100 mol % of a specific organic group having two benzene rings and 70-0 mol % of another specific divalent aromatic organic group, Z is a divalent organic group represented by the general formula (VI): ##STR2## wherein b is an integer of 5 to 80; and m and n each represent a number satisfying that m/(m+n) is 0.98 to 0.70 and n/(m+n) is 0.02 to 0.30; (B) an agent selected from a sensitizer and a photopolymerization initiator; and (C) an organic solvent. From this composition, polyimide films having a superior adhesion to substrates and also having no corrosive properties can be formed by low-temperature heat treatment.
