ABSTRACT:
New types of polymer latices and their use in photographic materials are disclosed. They are obtained by subjecting to radical emulsion polymerisation one or more radical-polymerisable monomers, whose emulsifier-free homopolymers or copolymers possess a glass transition temperature below 65.degree. C., preferably below 30.degree. C., in the presence of a water-soluble polymer of a particular chemical formula.
These new types of latices are preferably used in graphic arts contact materials, e.g. daylight materials. They can be used in relative high amounts thus improving dimensional stability without deteriorating the scratch resistance too strongly.
A preferred radical-polymerisable monomer mixture comprises n.-butyl acrylate, methyl methacrylate and acrylic acid.
