Abstract
There are disclosed a frost-coating composition, which comprises (i) a hydrophobic silica particle or further comprises (ii) a polymer particle, in addition to a photocurable compound; and a frosted glass container coated with such a composition. The frosted glass container coated with such a composition is excellent in alkali resistance, or excellent both in alkali resistance and in impact resistance.
Claims22
A frost-coating composition comprising 5-50 parts by weight of a hydrophobic fine silica particle based on 100 parts by weight of a photocurable compound, such that said frost-coating composition forms a frosted coating having enhanced alkaline resistance.
A frost-coating composition comprising 5-50 parts by weight of a hydrophobic fine silica particle and 3-30 parts by weight of a fine polymer particle based on 100 parts by weight of a photocurable compound, such that said frost-coating composition forms a frosted coating having enhanced alkaline resistance.
A frost-coating composition comprising 5-50 parts by weight of a hydrophobic fine silica particle based on 100 parts by weight of a photocurable compound, wherein the M value of the hydrophobic fine silica particle is 5 or more, such that said frost-coating composition forms a frosted coating having enhanced alkali resistance.
A frost-coating composition comprising 5-50 parts by weight of a hydrophobic fine silica particle and 3-30 parts by weight of a fine polymer particle based on 100 parts by weight of a photocurable compound, wherein the M value of the hydrophobic fine silica particle is 5 or more, such that said frost-coating composition forms a frosted coating having enhanced alkali resistance.
A method to obtain a frost-coating, which comprises applying to a substrate a frost-coating composition comprising 5-50 parts by weight of hydrophobic fine silica particles based on 100 parts by weight of a compound which is photocurable to provide an enhanced alkaline resistive frost-coating.
A method to obtain a frosted glass container comprising the steps of:
- preparing a frost-coating composition which comprises 5-50 parts by weight of a hydrophobic fine silica particle based on 100 parts by weight of a photocurable compound,
- coating the frost-coating composition on a glass container,
- curing a photocurable compound by irradiating the glass container coated with the frost-coating composition with an active energy ray, whereby said frost-coating composition forms a frosted coating having enhanced alkaline resistance.
