Embodiment 1

[0019] Add 5 g of sodium tetraborate (Na 2 B 4 o 7 ), 0.01 g of sodium dodecylbenzenesulfonate (C 18 h 29 SO 3 Na) and 10 grams of mannitol (C 6 h 14 o 6 ), prepared 1 liter of solution, and stirred for 5 hours to obtain an anti-pollution coating composition.

Embodiment 2 and 3

[0021] The process of Example 1 was repeated to obtain two antipollution coating compositions containing 15 grams and 20 grams of mannitol respectively.

Embodiment 4

[0023] 1 g of sodium tetraborate, 0.01 g of sodium dodecylbenzenesulfonate, and 1 g of mannitol were added to distilled water to prepare 1 liter of a solution, and stirred for 5 hours to obtain an anti-pollution coating composition. Comparative example 1

Abstract

The present invention relates to an aqueous antifouling coating composition comprising a water-soluble salt, a surfactant, and a sugar alcohol, and articles having an antifouling coating formed using the composition.

Description

technical field [0001] The present invention relates to an aqueous antifouling coating composition comprising a water-soluble salt, a surfactant, and a sugar alcohol, and articles having an antifouling coating formed using the composition. Background technique [0002] In order to prevent pollutants from adhering to the surface of glass or other substrates, a method has been proposed to form a water-soluble salt coating film thereon, and then, when necessary, clean the surface by washing the coating and pollutants with water (See Japanese Patent Application Laid-Open No. 11-35343). However, when only water-soluble salts are applied to the surface of the substrate, the coating becomes uneven and unsatisfactorily gives poor performance characteristics, especially when the coated substrate is processed at high temperatures. [0003] On the other hand, Japanese Patent Application Laid-Open No. 2000-211947 discloses a water-soluble protective film obtained using an aqueous solut...
