Monomers with cyclic carbonate groups of the formula I are suitable for the production of photosensitive recording materials, for example for the production of offset printing plates ##STR1## in which A means an (n+m)-valent hydrocarbon residue with 3 to 30 C atoms, which may be OH-substituted and may contain up to 8 ether bridges,

Monomers with cyclic carbonate groups

The invention relates to diacrylates and dimethacrylates which are derived from cyclohexyldiphenols. Di(meth)acrylates are used widely, for example, as a component of plastic filling materials in dental engineering.

Acrylates and methacrylates based on cyclohexyldiphenols

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.

An imaging element is disclosed comprising on a support a dye precursor and a color developer arranged in the same layer or in separate layers characterized in that a specific type of monomers according to one of formulas (I) or (II) and a photoinitiator is present in a layer containing said dye precursor and/or color developer. The imaging element of the invention can used as photosensitive as well as heat-sensitive imaging element for obtaining an image.
