Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A light-transmissive recording member, which comprises: a light transmissive substrate; an aqueous ink ink acceptor layer on the surface of said substrate, said ink acceptor layer being provided by a substantially continuous resin coating, said resin coating being about 1-200 μm thick; and a separate layer consisting essentially of powdery particles, said powdery particles being attached to the surface of said ink acceptor layer at a density of about 10-100 mg/m 2 , wherein said recording member has a linear transmission factor of at least about 2%.
Claim 2
Dependent Claim
