Abstract
Abstract A resinous composition is provided which is suitable for applying a transparent, non-fogging coating on a normally fogging substrate. The composition comprises a highly cross-linked alkylene imine polymer which is the reaction product of a polyalkylene imine polymer, a cross-linking compound containing a epoxy group and a an ethylenic unsaturated and another cross-linking compound containing a halogen group and an ethylenic unsaturated group.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A resinous composition having a high degree of cross-linking to attain water insolubility which comprises the reaction product of a polyalkylene imine polymer and at least two polyfunctional cross-linking compounds, one of said cross-linking compounds containing an epoxy group and an ethylenic unsaturated group and another of said cross-linking compounds containing a plurality of functional groups selected from the group consisting of a halogen group and an ethylenic unsaturated group, and said polyalkylene imine polymer being present in an amount of at least about 15% by weight, said cross-linking compound containing an epoxy group is present in an amount ranging from about 20 to about 60% by weight, said other cross-linking compound containing either a halogen group, an ethylenically unsaturated group or both is present in an amount ranging from about 10 to about by 40% by weight.
Claim 2
Dependent Claim
