    摘要: A composition comprising a condensation resin of the formula:R.sup.1 -A-Z[-A-Z'-].sub.n -R.sup.2wherein each A has the structure: ##STR1## and Y is a phenyl group or a methyl group; X is an alkylene group or an arylene group; R.sup.1 and R.sup.2 are each individually a C.sub.4 -C.sub.13 alkyl group, C.sub.4 -C.sub.12 alkyl group substituted with 1 or more hydroxy groups, or a combination thereof; n is 0, 1, or 2 provided that, when n is 0, then Z is a covalent bond, and when n is 1 or 2, then Z is a C.sub.4 -C.sub.13 alkylene group which is unsubstituted or substituted with 1 or more hydroxy groups; and Z' is the same as Z, a covalent bond or a derivative of the condensation resin. Along with an ink formulation comprising. The composition and method for preparing the above condensation resin having an increased softening temperature.
