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.
