Title: Transparent heat-sensitive recording medium
Inventor: SAWAMURA ICHIRO
IPC: B41M5/26
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To satisfy both the matching quality with a thermal head and the transparency by setting the uppermost surface roughness (ten point average roughness) at a specified value or above and the Haze at a specified value or below. SOLUTION: In the transparent heat-sensitive recording medium, first and second filters are added into a protective layer on a thermal recording layer thus setting the uppermost surface roughness (ten point mean roughness Rz) at 0.6 μm or above and the Haze at 30% or below. The first filter is added in order to impart absorbing power and heat resistance against thermally fused matters and the volume-average grain size thereof is preferably set at 0.5 μm or less. Too large grain size causes fog and damages transparency. The second filer is added in order to impart surface roughness and work-up cleaning performance and the volume-average grain size thereof is preferably set at 2 μm or above. The fillers can be selected from those commonly employed in this type of thermal recording medium.
