PURPOSE:To provide a photosensitive polyamide composition having enhanced photocrosslinking density and giving a proper relief by blending soluble polyamide with specified tri-, di- and monofunctional unsatd. monomers. CONSTITUTION:100pts.wt. soluble polyamide is blended with 0.5-20pts.wt. tri(meth)acryloylhexahydro-S-triazine, 0.5-20pts.wt. N,N'-hexamethylenebisacrylamide and 0.5-100pts.wt. one or more kinds of monofunctional unsatd. monomers selected from N-tert-butyl-(meth)acrylamide, (meth)acrylamide, N-methylol(meth) acrylamide and diacetoacrylamide. In this range of blending ratio the compatibility of the polyamide with the unsatd. monomers is improved. The resulting composition is not swollen even by elution and can be dried in a short time. Thus, a relief having a proper shoulder angle is obtd. |
