Abstract

968, 706. Photolithographic printing plates. GEVAERT PHOTO-PRODUCTEN N.V. June 2. 1961, No. 20072/61. Heading-G2M. A lithographic lacquer containing a reaction product of formaldehyde with a phenol or an alkyl substituted phenol is applied to a silver image formed by the diffusion transfer process to increase into receptivity of such image. A lithographic preparation may be applied before application of the lacquer. The silver image may be formed on an aluminium sheet and rubbed with wadding impregnated with an aqueous composition comprising carboxymethyl cellulose, sodium phosphate, phospheric acid, cetyl trimethyl ammoniumbromide and formaldehyde and is then rubbed with a cyclohexanone solution of a proprietary alkyl phenol resin containing also a rhodamine and may be rubbed again with the aqueous carboxymethyl cellusose solution. Specification 913, 591 is referred to.
