Abstract
Disclosed herein is an anti-fogging coating material comprising at least one selected from the group consisting of an inorganic alkoxide, a hydrolysate of the inorganic alkoxide and a polycondensate of the hydrolysate of the inorganic alkoxide, a polyacrylic, and polyvinyl alcohol.
Claims14
An anti-fogging coating material comprising a solution which comprises:
- i) at least one composition selected from the group consisting of an inorganic alkoxide, a hydrolysate of the inorganic alkoxide and a polycondensate of the hydrolysate of the inorganic alkoxide;
- ii) a polyacrylic;
- and
- iii) polyvinyl alcohol.
An anti-fogging coating film formed by using, as a main component, a composition obtained by a polycondensation reaction of a hydrolysate of an inorganic alkoxide in the presence of a polyacrylic and polyvinyl alcohol.
An anti-fogging coating film formed by using, as a main component, a composition obtained by a polycondensation reaction of a hydrolysate of an inorganic alkoxide in the presence of a polyacrylic, polyvinyl alcohol and hydrosilicofluoric acid.
An anti-fogging coating film formed by using, as a main component, a composition obtained by a polycondensation reaction of a hydrolysate of an inorganic alkoxide in the presence of a polyacrylic, polyvinyl alcohol, hydrosilicofluoric acid and a silane coupling agent having an epoxy group.
An anti-fogging coating film formed by using, as a main component, a composition obtained by a polycondensation reaction of a hydrolysate of an inorganic alkoxide in the presence of a polyacrylic, polyvinyl alcohol and a benzophenone compound represented by the formula
- wherein X1 to X10, which may be the same or different from one another, are each a group selected from the group consisting of hydrogen, a hydroxyl group, a sulfonic acid group, a carboxyl group, an acyl group, an ester group, an ether group, hydrocarbon groups, alkoxyl groups having 1 to 6 carbon atoms, an amino group, hydroxyalkyl groups and hydroxyalkoxyl groups, with the proviso that at least one of X1 to X10 is a group selected from the group consisting of a hydroxyl group and a sulfonic acid group.
