| titleOfInvention | Photosensitive composition for the production of high-quality color CRT black matrix |
| abstract | The present invention relates to a new photosensitive composition that can be used in the process of forming a black matrix in the production of color CRT, and to a new photosensitive composition which synthesizes a new water-soluble polymer and uses the synthesized water-soluble polymer. The stability has been greatly improved, and the service life of about 3 times more than that of the conventionally used product is secured. Advantages of the present invention are improved sensitivity compared to the former, compared to the latter compared to the polyvinylpyrrolidone and bis azide mixed composition or acrylamide-diacetoneacrylamide copolymer and bisazide mixed composition used in the past The improvement of the ease of peeling and storage stability of the photosensitive composition was brought. Therefore, the photosensitive composition obtained by this invention is excellent in film | membrane characteristic, the sensitivity can be improved, and the advantage which can stably produce high quality CRT tube can be ensured.n n n The polymer synthesized in the present invention is a vinylpyrrolidone-acrylamide copolymer, which is a water-soluble polymer having upper half non-uniformity. Since the existing product uses a silane adhesion improving agent that can bring about a deformation of the product and lacks stability, the stability can be greatly improved by adding amines used as the additive of the present invention. |
