Patent number: 5240808Abstract: A light-sensitive composition which comprises at least one polymeric compound having both photocross-linkable groups and functional groups carrying P--OH bonds. The light-sensitive composition can effectively be employed for making lithographic printing plates, IC circuits and photomasks. The light-sensitive composition shows excellent practically acceptable developability with either of an aqueous alkali developer and an aqueous alkaline solution containing or free of organic substances such as organic solvents and/or surfacants. Moreover, when it is used to form PS plates, the resulting lithographic printing plates never cause background contamination and can provide a large number of good printed matters. The composition makes it possible to develop negative working PS plates with developers for positive working PS plates. Therefore, when both positive and negative working PS plates are processed, the use of the composition can save various troubles.Type: GrantFiled: January 8, 1992Date of Patent: August 31, 1993Assignee: Fuji Photo Film Co., Ltd.Inventors: Keitaro Aoshima, Masanori Imai
