Abstract
1523877 Developing photo-sensitive polymers VICKERS Ltd 19 Nov 1975 [19 Sept 1974] 40949/74 Heading G2C A developer for an exposed photo-sensitive polymer layer includes a lactam of the Formula: in which n is 0 or an integer of from 1 to 9; h is a hydrogen atom, or an alkyl, alkenyl, aralkyl, aryl or acyl group; and R' and R" are each a hydrogen atom or an alkyl or aryl group, together with a wetting agent and/or a colourant. The colourant is preferably an organic solvent soluble dye. Preferred lactams are 1-methyl-2pyrrolidinone, 1-butyl- 2-pyrrolidinone, 1-cyclohexyl-2-pyrrolidinone, 2-pyrrolidinone, 1-vinyl-2-pyrrolidinone and #-caprolactam. The developer may further include (i) an acid e.g. phosphoric, hydrochloric [or] sulphuric, acetic, lactic, glycollic or α-pentenoic acid (ii) an inert diluent e.g. water, ethanolamine or 2-ethoxy ethanol and (iii) an additional organic solvent which dissolves the polymer e.g. tetrahydrofurfuryl alcohol, 2-methoxy ethyl acetate or γ-butyrolactone. The light-sensitive polymer is negative working containing groups of the structure -CH=CH-CO- e.g. polyvinyl cinnamate, or a cinnamoylated epoxy resin.
