MAKING METHOD FOR PHOTOSENSITIVE RESIN PLATE

摘要

PURPOSE:To make the photosensitive resin plate of high thickness accuracy and high resolving power by interposing a plastic film between liquid-form photosensitive resin and negative film and exposing the same in exposure process. CONSTITUTION:The plastic film composed of the mixture of crystalline 1,2-polybutadiene of crystallinity about 5-45% and intrinsic viscosity (30 deg.C in toluene) about 0.5% or more and about 5-70wt% thereof of the (co)polymer of unsaturated compounds shown by the formula is sandwiched between liquid-form photosensitive resin and negative film and is used. The thickness of the above-mentioned film is preferably 0.005-0.1mm.
