Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
167 words
An ink jet recording sheet consisting essentially of a transparent support and, provided thereon, at least one ink-receiving layer which is a light transmission layer obtained by coating and drying an emulsion polymerized composition obtained by emulsion polymerization of (a) 100 parts by weight of a compound represented by the formula: ##STR5## wherein R 1 represents a hydrogen atom, a methyl group, an ethyl group or a propyl group; R 2 represents a hydrogen atom r an alkyl group of 1-5 carbon atoms; and n represents an integer of 1-20 or (b) 100 parts by weight in total of the compound of the formula (I) and a compound represented by the formula: ##STR6## wherein R 1 is as defined above; and R 3 represents an alkyl group of 1-18 carbon atoms, with a proviso that the amount of the compound of the formula (II) is not more than that of the compound of the formula (I); and 30-100 parts by weight of polyvinyl alcohol as an emulsifier.
Claim 2
Dependent Claim
167 words
An ink jet recording sheet consisting essentially of a transparent support and, provided thereon, at least one ink-receiving layer which is a light transmission layer obtained by coating and drying an emulsion polymerized composition obtained by emulsion polymerization of (a) 100 parts by weight of a compound represented by the formula: ##STR5## wherein R 1 represents a hydrogen atom, a methyl group, an ethyl group or a propyl group; R 2 represents a hydrogen atom r an alkyl group of 1-5 carbon atoms; and n represents an integer of 1-20 or (b) 100 parts by weight in total of the compound of the formula (I) and a compound represented by the formula: ##STR6## wherein R 1 is as defined above; and R 3 represents an alkyl group of 1-18 carbon atoms, with a proviso that the amount of the compound of the formula (II) is not more than that of the compound of the formula (I); and 30-100 parts by weight of polyvinyl alcohol as an emulsifier.

An ink jet recording sheet according to claim 1, wherein the emulsion polymerized composition has a viscosity of 80-2000 cps measured at a concentration of 20% and a temperature of 20° C. at the time of application to the support has been added.
Claim 6
Dependent Claim
21 words
A process for ink jet recording wherein an aqueous ink is applied to the ink jet recording sheet of claim 1.
