PURPOSE:To obtain the titled composition having no tackiness, a high resolution and a high density and capable of etching by incorporating a polymer which is obtd. by reacting isocyanate ethyl methacrylate to a specific vinyl type linear polymer and a specific glass transition temp., and a photosensitizer to the titled composition. CONSTITUTION:The titled composition comprises the polymer which is obtd. by reacting isocyanate ethyl methacrylate to the vinyl type linear polymer obtd. by copolymerizing 5-85wt% a compd. contg. each one of vinyl and hydroxy groups in a molecule, 10-40wt% a compd. contg. one of vinyl group and a carboxyl group in a molecule, and <=80wt% a compd. having one of the vinyl group in a molecule, in 0.3-1.3 an equivalent ratio of an NCO group to an OH group of said polymer, and also has the glass transition temp. of 40-130 deg.C, and the sensitizer capable of forming a free radical with an active ray. As the composition has no tackiness, an exposure, a development and an etching may be performed by directly laminating a negative film on said composition, without contaminating the negative film. The composition is suitable to obtain a distribution panel having a resolution and a high density. |
