Abstract
(EN)
[Problem] To provide a resin composition for forming a cured film that forms a lower layer and an upper layer of a color filter. [Solution] A resin composition which contains a homopolymer that has a structural unit represented by formula (1), a crosslinkable compound that has at least two alkoxyalkyl groups in each molecule, a photoacid generator, a surfactant and an organic solvent, wherein: the content of the crosslinkable compound is from 40% by mass to 60% by mass relative to the content of the homopolymer; and the content of the photoacid generator is at least 0.8% by mass relative to the total content of the homopolymer and the crosslinkable compound. (In the formula, R1 represents an alkyl group having 1-6 carbon atoms, which comprises at least one hydroxy group as a substituent.)

Le problème décrit par la présente invention est de fournir une composition de résine servant à former un film durci qui forme une couche inférieure et une couche supérieure d'un filtre coloré. La solution selon l'invention porte sur une composition de résine qui contient un homopolymère qui comporte un motif structural représenté par la formule (1), un composé réticulable qui possède au moins deux groupes alcoxyalkyle dans chaque molécule, un photogénérateur d'acide, un tensioactif et un solvant organique. La teneur en composé réticulable est de 40 % en masse à 60 % en masse par rapport à la teneur en homopolymère ; et la teneur en photogénérateur d'acide est d'au moins 0,8 % en masse par rapport à la teneur totale en homopolymère et en composé réticulable. (Dans la formule, R1 représente un groupe alkyle possédant de 1 à 6 atomes de carbone, qui comprend au moins un groupe hydroxyle en tant que substituant).
