ABSTRACT:
Compositions to be applied to professional studio photographs on color paper or black and white emulsions for protective and finishing purposes comprising a vinyl resin in particulate form dispersed in methyl isobutyl ketone to which is added a blend of aromatic hydrocarbons such as naphtha and xylene, with or without a thinning or flattening agent, and a plasticizer. The compositions are also useful for preventing color changes and for making color corrections. They overcome the yellowing and other disadvantages of conventional lacquers such drying hard and cracking the photographic print.
