Definitions

  • cyclic compound examples include benzotriazoles, 5-phenyl-1 H-tetrazole and
  • a radiation-to-heat converting compound(C) capable of absorbing incident radiation, preferably infrared radiation, and converting it to heat, is preferably incorporated in the coating composition.
  • the radiation-to-heat converting compounds suitable for the invented heat-sensitive compositions may be chosen from a wide range of organic and inorganic pigments such as carbon blacks, phthalocyanines or metal oxides.
  • Acetalization of the polyvinyl alcohols takes place according to known standard methods as described, for example, in U.S. Pat. No. 4,665,124; U.S. 4,940,646; U.S. 5,169,898; U.S. 5,700,619; U.S. 5,792,823; JP 09,328,519 etc.
  • Levanon et al. provide detailed synthesis examples for the acetal polymers used in the present invention.
  • a coating was made with the composition:
  • Two plates were cast manually, one with the above solution containing Zelec 8172 as a development-enhancer and one with the reference solution in Example 28 without development-enhancer.
  • the plates had a coating weight of 1.7-1.8 g/m 2 .
  • the plates were dried at 125°C, 2min and imaged with 12 W an energy series between 80- 300mJ/cm 2 .
  • the plates were developed in 60% Goldstar at 23°C, 30 s.
  • the clearing point and % weight loss in developer were 140 mJ/cm 2 and ⁇ 50, respectively for the plate containing Zelec 8172 while the reference plate without developability-enhancing compound did not clear up to 300 mJ/cm 2 .
  • the coating solution in this example and the reference coating (as in Example 28) were made in acetone: Dowanol PM, 75:25 at 10% solids.
  • the solutions were cast with a rod on anodized aluminum substrate.
  • the resulting plates were baked at 130°C for 3 min.
  • the coating weight was 1.7 g/m 2 .
  • the plates were exposed to a 830 nm IR laser radiation at a power of 8W and an energy density series of 90-400 mJ/cm 2 .
  • the plates were developed in a DuPont-Howson processor in a developer containing 7% sodium metasilicate of conductivity 71 mS/cm in the following conditions: 23°C and 30 s residence time.
  • the plate with resorcinol developability-enhancing compound had a clearing point of 15QmJ/em 2 and a non-irradiated % coating weight loss of ⁇ 50 as compared to 350 rnJ/cm 2 and a non-irradiated % coating weight loss of ⁇ 50 for the reference plate.

Abstract

L'invention concerne une composition sensible au rayonnement, positive, destinée à être utilisée avec une source de rayonnement, qui comprend au moins un polymère acétal de polyvinyle pouvant être dissout dans une solution aqueuse alcaline et un composé améliorant le développement. La sensibilité d'un revêtement sensible au rayonnement basé sur la composition de cette invention est augmentée sans compromettre les caractéristiques de manipulation. Des éléments sensibles au rayonnement basés sur la composition de cette invention possèdent une bonne latitude de développement. Un précurseur d'impression lithographique positif est basé sur cette composition sensible au rayonnement enduite sur une surface hydrophile. Ce précurseur peut être développé au moyen d'une solution aqueuse alcaline, et peut être utilisé avec une source de rayonnement dans des applications lithographiques telles que des systèmes d'imagerie conventionnels, des systèmes directs de l'ordinateur à la plaque ou d'autres applications d'imagerie directe. Ce précurseur est stable dans son état précédant l'exposition et possède une excellente propriété de manipulation.
