The present invention is directed to polymeric compounds comprising a main backbone derived from at least the following monomeric components: (I) 20 to 99.9% by weight, preferably 50% to 99% by weight, of at least one cationic monomer according to formula (I), and (II) 0.1 to 80% by weight of a hydrophobic unsaturated nonionic monomer that polymerizes in the presence of an initiator, optionally a water-soluble monomer (III) different from either monomer (I) and monomer (II), and optionally a crosslinking agent (IV). Said compounds are particularly useful to overcome the problem of dye bleeding and/or dye transfer in laundry processes.

Fluorinated polymers useful in photoresist compositions and associated processes for microlithography are described. These polymers and photoresists have a fluoroalcohol functional group that simultaneously imparts high ultraviolet (UV) transparency and developability in basic media. The polymers also have a repeat unit derived from a C1-C25 alkyl hydroxymethylacrylate comonomer, e.g., tert-butyl hydroxymethylacrylate, or a C5-C50 polycyclic alkyl acrylate in which the polycyclic group contains a hydroxy group, e.g., hydroxyadamantyl acrylate. The materials of this invention have high UV tansparency, particularly at short wavelengths, e.g., 193 nm and 157 nm, which makes them highly useful for lithography at these short wavelengths.

The present invention relates to the use of acrylate copolymers, which provide excellent water resistance to personal care products without the undesirable waxy, greasy or heavy feel. Further, these acrylate copolymers are easy for manufacturers to use as they can be easily incorporated into the water phase without special processing.
