REVERSIBLE HEAT-SENSITIVE RECORDING MATERIAL

摘要

PURPOSE:To provide a reversible heat-sensitive recording material which has favorable contrast between transparency and cloudiness and is superior in recovery to a mechanical deformation and free form generation of a harmful substrance by thermal decomposition. CONSTITUTION:This is a reversible heat-sensitive recording material obtained by providing a heat-sensitive layer consisting mainly of a resin basic material comprised of polyurethane whose glass transition point is at least 35 deg.C and an organic low molecular-weight substance dispersed within the resin basic material and changing reversibly transparency by depending on a temperature.
