Abstract: The present invention provides a process for generating mixed acetal polymers by reacting a hydroxyl containing polymer or monomer with vinyl ether and alcohol in the presence of an acid catalyst. The process of this invention provides a new class of polymers based on mixed acetals which are prepared in-situ with one reaction. The mixed acetal polymers are inexpensive to synthesize and readily reproducible. The resulting mixed acetal polymer is blended with a photoacid generator and dissolved in a solvent to produce a chemically amplified resist composition. A process for forming a pattern comprises the steps of providing the chemically amplified resist composition, coating a substrate with the resist composition, imagewise exposing the resist coated substrate to actinic radiation, and forming a resist image by developing the resist coated substrate.

Abstract: A yellow, hot melt alkyd traffic marking composition is described. The yellow, hot melt alkyd traffic marking composition contains 10-25 percent by weight of a hot melt alkyd binder, 5-10 percent by weight of a thermally stable 1,5- or 1,8-substituted anthraquinone colorant selected from a 1,5- or 1,8-substituted anthraquinone aromatic thioether and a 1,5- or 1,8-substituted anthraquinone aromatic thioether polyester, and 65-85 weight percent of a filler. The yellow, hot melt alkyd traffic marking composition of the invention may also contain other components used in traffic marking compositions, such as a reflectivity aid, a plasticizer, or an impact modifier. Other optional components are discussed below. The yellow, hot melt alkyd traffic marking compositions may be applied to any paved surface.
