| 摘要 |
<p>The present invention relates to a resinous copolymer comprising monomer units of each of the groups of phenol compounds (I) and olefinically unsaturated non-acidic terpene compounds (II), characterized in that the copolymer contains monomer units from the group of polyunsaturated olefin compound (III), the monomer units of compound (III) being 1 to 70 % by weight of the total of the monomer units of compounds (II) and (III), the monomer units of compounds (II) and (III) being at least 50 % by weight of the total of the monomer units of compounds (I), (II) and (III). The melting point of the copolymer is at least 130 °C. The copolymers can be used in printing inks.</p> |
