Abstract (en)
The novel feature in a pressure-sensitive recording material contg. micro-encapsulated, solvent-dissolved 3.1-benzoxazine colour donors of formula (I) is that the solvent is (or contains) one or more natural oils and/or fatty acid-based esters of natural oils. In (I), A = X<2>-pC6H4- or a gp. of formula (II); B = a gp. of formula (II) or (R<6>)(R<7>)N-pC6H4-; X<1> = H, halogen, NO2, CN, 1-4C alkyl, OR<8> or NR<9>R<10>; X<2> = H, halogen, 1-4C alkyl or -OR<8>; R<1>-R<3> = H, halogen, 1-4C alkyl or -OR<8>; R<4>-R<10> = 1-8C alkyl, cyclohexyl, benzyl or phenyl, with -NR<6>R<7> and -NR<9>R<10> opt. also being pyrrolidino, piperidino or morpholino; with the proviso that the following combinations of values does not occur: A = X<2>-pC6H4-; B = (R<6>)(R<7>)N-pC6H4-; X<1> = dimethylamino; X<2> = MeO; R<3> = H; R<6> and R<7> = Et; and one of R<1> and R<2> = Me and the other = H.
