    摘要: Low-color polymer solutions, dispersions, emulsions and films containing iron compounds are provided. A method for reducing or eliminating the discoloration of polymer solutions, dispersions, emulsions and films due to iron-containing compounds is accomplished by additives at a level of from 10 to 5,000 ppm based on the polymer. These low-color polymers are particularly useful in coating applications, such as latex paints.

    摘要: A positive-acting photoresist composition which produces crosslinked images and processes for using the photoresist composition are disclosed. The photoresist composition is prepared from a mixture containing a film-­forming, polymer-containing, acid-hardening resin system, an acid or acid-­generating material for crosslinking the acid-hardening resin system, and a photobase generating compound. The photoresist composition is applied to a substrate surface and selectively imagewise exposed through a photomask to actinic radiation. The actinic radiation causes the photobase generator to produce a base in the imagewise exposed portions of the photoresist film. The photochemically generated base neutralises the acid in the imagewise exposed areas of the photoresist film. The non-imagewise exposed portions of the photoresist film, not containing the photochemically generated base, are crosslinked by the catalytic action of the acid upon heating the film, and the imagewise exposed portions of the photoresist film are removed from the substrate by the action of a developer solution leaving a crosslinked positive image on the substrate.

    摘要: This invention is concerned with photosensitive polymer compositions useful in the preparation of printed circuit boards, lithographic printing plates, cathode ray tubes, as well as in chemical milling, solder resist and planarizing layer applications. The photosensitive polymer compositions comprise a crosslinkable photosensitive polymer composition, which comprises (a) photoinitiator, and (b) at least one polymer having one or more carrier groups per polymer molecule, and wherein the composition contains unsaturated groups so that it is capable, upon exposure to actinic radiation, of forming a film containing crosslinked polymer. The photosensitive polymer compositions, conveniently in the form of aqueous solutions or emulsions, are capable of being electrophoretically deposited as adherent, uniform, photosensitive films on conductive surfaces. Films formed from the photosensitive polymer compositions can be aqueous developable and resistant to strong inorganic acids and strong bases.
