The invention is directed to compositions on a surface which comprise a) at least a (meth)acrylate prepolymer, wherein Q, R, R, R, R, m and n are defined herein. Further the compositions may be used to improve the adhesion to surfaces, especially metallic surfaces and may include additional optional components such as adhesion promoting photoinitiators.

(Meth)acrylate phosphonic esters as adhesion promoters

Compounds containing both photoinitiator moieties and adhesion promoting moieties and coating formulations containing them are disclosed, in particular, durable UV cured primer layers for coil coatings. One embodiment includes a coated metal surface which comprises a metal substrate with at least one surface immediately adjacent to a coating layer comprising a photoinitiator chemically bound to an adhesion promoter is disclosed.

Adhesion promoting photoinitiators for UV cured coatings over metal surfaces

Novel stabilizers that are comprised of known polymer additive moieties chemically bound to hyperbranched and/or dendritic polymers or copolymers, and novel stabilizers comprised of known polymer additive moieties chemically bound to amphiphilic copolymers exhibit superior permanence in an organic substrate as well as high surface affinity.

Polymer additives with improved permanence and surface affinity

A process for dyeing or printing an article comprising a hydrophobic polymer, wherein the hydrophobic polymer is brought into contact with a condensation polymer obtained by condensation of at least one poly-hydroxyl-mono-carboxylic acid, prior to or simultaneously with the treatment of the article with a color imparting compound, with the proviso that the condensation polymer is not terminated with lipophilic groups. The process provides dyed articles with good fastness properties.
