    Abstract: PURPOSE: To continuously produce a multilayered photosensitive recording element by a simple and economical method by melting components to be used in the production of the individual layers of a photopolymerizable recording layer in one screw extruder to mix them. CONSTITUTION: A component mixture comprising components (a), (b) is degassed at a degassing position and, next, about 5% of the component mixture is taken out of an extruder in front of a re-supply member 4. This partial flow is supplied into a bypass pipe by using a gear pump 5 and the component mixture is supplied to a multilayered nozzle 6 by a static mixer 7. A component (d) is supplied to the component mixture remaining in the extruder and this mixture is degassed in front of a kneading member 8 to be supplied to the multilayered nozzle 6. Individual layers are formed within the multilayered nozzle from mass flows (e), (f) to be mutually bonded. The obtained composite is rolled. By this method, a recording element having a photopolymerizable recording layer consisting of individual layers having different properties can be produced.

    Abstract: PURPOSE: To make the copying performance of a printing plate unchanged, especially, even after the process to develop an image with an alkaline developing solution for a long time by aftertreating the printing plate with an aqueous solution of a silane hydrolysate and, in addition thereto, an aqueous solution of free fluoride. CONSTITUTION: When treating an aluminum oxide layer with at least, an aqueous solution of one kind of silane hydrolysate and/or a condensate as shown by a formula, the aqueous solution contains at least, one kind of chemical compound of MF or M2 XF6 (M is an alkaline metal and X is Ti, Zr or Si). In a formula I, R and R are each a 1-9C alkyl group or the like; and X is one of the groups represented by a formula II, wherein, R is a hydrogen, a 1-9C alkyl group, a carboxylic acid group or a carboxylic acid anhydride formed by a formula III bonded with the carboxylic acid group and R . R and R are each 1-9C alkyl group or the like; R is a hydrogen or a 1-9C alkyl group; Z is a hydrogen or an alkaline metal; Hal is a chlorine or a bromine; y is 1-4 and: n is 0.1 or 2.
