Color concentrates and polymer compositions containing the same, and methods of making the same

A method of preparing a color concentrate comprising the steps of:

• i. providing at least one resin selected from the group consisting of a homopolymer of a diene, a rosin material, a coumarone-indene resin, a polymer of a vinyl aromatic monomer having an Mn of from about 500 to about 4000 and mixture of resins (a) having a melt viscosity from about 500 to about 3000 poise at 110.degree. C. at a shear rate of 100 sec.sup.-1 ;
• ii. providing at least one resin selected from the group consisting of a copolymer of an olefin and an acrylate or a methacrylate, a polymer of a vinyl aromatic monomer having an Mn of at least about 10,000 and mixture of resins (b) having a melt index from about 0.5 to about 50 gmB 10 minute;
• iii. providing at least one organic colorant or mixture of organic colorants;
• (c) and
• iv. mixing by weight from about 5% to about 25% of said component (a) with from about 1% to about 25% of said component (b) and from about 25% to about 95% of said component (c) so as to provide said color concentrate wherein the color concentrate prepared is free of wax.
