Definitions

• Photosensitive materials comprising a polyvinylbutyral lacquer and an aliphatic alkaryl, dimethyl ammonium bichromate.
• An example is dimethyllaurylbenzyl ammonium bichromate.
• the invention relates to the preparation of a photosensitive polyvinylbutyral lacquer which contains a waterinsoluble polyvinylbutyral resin and a bichromate. Such lacquers are used in photomechanical processes.
• photosensitive lacquer of this type may particularly advantageously be prepared by using a water-insoluble or substantially water insoluble organic bichromate which, however, is readily soluble in solvents in which the polyvinylbutyral resin is soluble.
• R may be an aliphatic saturated or unsaturated hydrocarbon chain having 6 to 18 carbon atoms or an alicyclic ring. If n is smaller than 3, the various hydrocarbon radicals R may be ditferent or the same.
• Examples of such compounds are dimethyldilauryl ammonium bichromate and trimethyllauryl ammonium bichromate.
• R is an aliphatic hydrocarbon moiety of 6-18 carbon atoms inclusive and R is alkaryl of 7 to 12 carbon atoms inclusive.
• R may be for example, octyl, decyl, dodecyl (lauryl), tetradecyl (myristyl) hexadecyl (cetyl), octadecyl (stearyl).
• polyvinylbutyral vinyl alcohol content approximately 20% by weight, viscosity of a standard solution of 10% by weight of polyvinylbutyral in methanol: cm. at 25 in a mixture of 75 mls. of dimethylformamide and mls. of butanone.
• This layer was exposed to light through a template for 1 minute by means of four 125 watt high pressure mercury discharge lamps placed in the corners of a square having sides of 15 cms. at a distance of 50 cms. from the object. The unexposed parts of the lacquers were then washed away in methanol. The remaining lacquer pattern may be used as a screening layer for various etching or electro-deposition processes.
• R is an aliphatic hydrocarbon chain of 6 to 18 carbon atoms and R is aralkyl of 7 to 12 carbon atoms.
