Abstract
Abstract Aromatic bis-acrylic derivatives of the formula: WHEREIN Y1 and Y2 each represent a GROUP, AND R and X are each a hydrogen atom or a lower alkyl group; a process for their preparation, and photosensitive ccompositions comprising such derivatives in admixture with linear polyamides in molar ratios of 2:1-1:100.
