A base material having a dyed surface is obtained by applying to the surface of a base material photo-reactive resin composition (D) containing: (a) a copolymer (A) between a vinyl monomer having a photosensitive group and a copolymerizable vinyl monomer having a group with an affinity for an anionic dye; (b) a photo-reaction initiator (B) as an optional component; and (c) a solvent (C), to form a film, irradiating it with actinic light, and dyeing the film with an anionic dye. This material is useful as a color filter for a liquid crystal color television, etc. Un matériau de base possédant une surface colorée est obtenu en appliquant à la surface d'un matériau de base une composition à base de résine photoréactive (D) contenant: a) un copolymère (A) entre un monomère vinylique possédant un groupe photosensible et un monomère vinylique copolymérisable possédant un groupe avec une affinité pour un colorant anionique; b) un initiateur de photoréaction (B) en tant que composant facultatif; c) un solvant (C), de manière à former un film, et en l'irradiant avec une lumière actinique et en colorant le film avec un colorant anionique. Ce matériau est utile en tant que filtre de couleurs pour un écran de télévision couleurs à cristaux liquides, etc.
