    Abstract: PURPOSE: To ensure satisfactory stability in a rolled state even at the time of storage of a dry film resist over a long period of time by allowing a specified N-vinylamide copolymer or a polyamide additive to exist in a photopolymerizable recording layer. CONSTITUTION: The top of a carrier having dimensional stability is coated with a photopolymerizable recording layer developable with an aq. alkali soln. and contg. a polymer binder, at least one kind of ethylenic unsatd. photopolymerizable compd. and at least one kind of photoinitiator or further contg. other additives and/or auxiliaries. In the recording layer, an N-vinylamide homopolymer, an N-vinylamide copolymer contg. >=50mol% N-vinylamide units in a polymerized state or a polyamide additive having 1,500-300,000g/mol mol.wt. exists by 0.2-6wt.% of the total amt. of the recording layer. Laminating is facilitated and stability in a rolled state can be improved even at the time of storage of a dry film resist over a long period of time.

    Abstract: PURPOSE: To improve reproducibility and resolution by using specific compds. in order to suppress the dissolution of a binder in an aq alkaline soln. CONSTITUTION: The good reproducibility and high resolution are obtd. by using the binder or binder mixture which is soluble in the aq. alkaline soln. and is the monoketal of a β-dicarbonyl compd. of formula I. In the formula I; R and R may be the same as or different from each other and respectively signify alkyl, cycloalkyl, aralkyl and, in some cases, aryl substd. with alkyl or halogen. R signifies hydrogen, halogen, alkyl, cycloalkyl, aralkyl, and, in some cases, aryl substd. with alkyl or halogen. Or R together with R , R with R or R with R may form a 5- or 6-membered ring; R and R may be the same as or different from each other and respectively signify alkyl, cycloalkyl or aralkyl or R and R may combine to form a 5- or 5-membered ring.

    Abstract: PURPOSE: To improve suitability to exposure by using a specified dye forming compsn. or further using a film forming polymer binder, a compd. having an ethylenic unsatd. double bond, a photopolymn. initiator activated by irradiation with chemical rays or its compsn., additives and auxiliaries. CONSTITUTION: This photosensitive compsn. contains a mixture of at least one kind of hexaarylbisimidazole compd. represented by formula I or its structural isomer with at least one kind of halogen-contg. compd. represented by formula II and at least one kind of dye forming compd. convertible into a dye by oxidation as a dye forming compsn. In the formula I, Ar is optionally substd. phenyl and Ar is phenyl or phenyl substd. by halogen or alkyl at the 2- or 2'-position. In the formula II, Hal is halogen and R is H, optionally substd. alkyl, cycloalkyl, aryl, heteroaryl or a heterocyclic group. This compsn. has satisfactory suitability to exposure, forms a very fine image faithful to the original and can guarantee sure reproduction.
