Abstract
An ink-jet recording sheet is provided with at least one ink-receiving layer on at least one side of a base material sheet. A resin component which constitutes the ink-receiving layer comprises a hydrophilic resin containing tertiary amino groups in a molecule thereof or a hydrophilic resin containing tertiary amino groups and polysiloxane segments in a molecule thereof. A coating formulation suitable in use for the production of the ink-jet recording sheet is also disclosed.
Claims17
An ink-jet recording sheet provided with at least one ink-receiving layer on at least one side of a base material sheet, wherein a resin component which constitutes said ink-receiving layer comprises a hydrophilic resin containing tertiary amino groups and polysiloxane segments in a molecule thereof, wherein said hydrophilic resin has a weight average molecular weight of from 5,000 to 500,000.
An ink-jet recording sheet provided with at least one ink-receiving layer on at least one side of a base material sheet, wherein a resin component which constitutes said ink-receiving layer comprises a hydrophilic resin containing tertiary amino groups and polysiloxane segments in a molecule thereof, wherein said hydrophilic resin contains tertiary amino groups in a proportion of from 0.1 to 50 equivalents per grams.
An ink-jet recording sheet provided with at least one ink-receiving layer on at least one side of a base material sheet, wherein a resin component which constitutes said ink-receiving layer comprises a hydrophilic resin containing tertiary amino groups and polysiloxane segments in a molecule thereof, wherein said hydrophilic resin contains polysiloxane segments at a content of from 0.1 to 10 wt. %.
