Patent number: 4168173Abstract: It has been found that high quality relief printing plates can be made using a photosensitive composition comprising at least one unsaturated polyester, at least one ethylenically unsaturated, addition polymerizable monomer, at least one photosensitive initiator and a poly(hydroxylether) derived from a diphenol and an epihalohydrin, such as bisphenol A-epichlorohydrin resin. The poly(hydroxylether) increases the viscosity of the photosensitive resin such that the resin is less likely to flow during platemaking process, thereby avoiding undesirable blemishes on the finished plate.Type: GrantFiled: September 7, 1978Date of Patent: September 18, 1979Assignee: Hercules IncorporatedInventor: Rudolph L. Pohl
