Abstract

1. Body with reversible, fixed and temperature-variable light extinctions, especially for the use as erasable record carrier, consisting of a pair of materials (A and B), one material (A) of which consists of at least one polymer and/or resin matrix material and which when heated from the state of maximum light extinction to a clear temperature (T1 ) lying below a conversion temperature (T2 ) and subsequently cooled off below a low temperature (T0 ) yields light extinctions which become smaller with increasing heating temperature (T), and when heated to a temperature between T1 and T2 and subsequently cooled below T0 yield minimum light extinction, whereby when heated above the conversion temperature (T2 ) lying above T1 and subsequently cooled below T0 again maximum light extinction is obtained, characterized in that the other material (B) of the pair of materials is at least one organic low-molecular substance which is contained in the material (A) at least partially as dispersed second phase and which is an alkanol, alkandiol, haloalkanol or haloalkandiol, alkylamine, alkane, alkene, alkine, haloalkane, haloalkene or haloalkine, cycloalkane, cycloalkene or cycloalkine, a saturated or unsaturated mono- or dicarboxylic acid or an ester or an amide or an ammonium salt thereof, a saturated or unsaturated halogen fatty acid or an ester, an amide or an ammonium salt thereof, an arylcarboxylic acid or an ester, and amide or an ammonium salt thereof, a haloarylcarboxylic acid or an ester, an amide or an ammonium salt thereof, a thioalcohol, a thiocarboxylic acid or an ester, an amide or an ammonium salt thereof or a carboxylic acid ester of a thioalcohol or mixtures of these compounds, each of which has 10 to 60, preferably 10 to 38, especially 10 to 30 carbon atoms, whereby in the esters the alcohol group may be saturated or unsaturated and/or halogensubstituted.
