Embodiment approach

[0133]In one embodiment of the biotoner of the present invention there is provided a biotoner comprising a bioresin, a second resin and one or more colorants, wherein the biotoner is a polyester polymer , which comprises one or more reacted diacid monomer units and one or more reacted diol monomer units, and wherein at least one of the reacted diacid monomer units or the reacted diol monomer At least one of the units is a biomonomer obtained from a plant or animal source. Preferably, the softening point of the bio-resin is from about 80°C to about 170°C. More preferably, the bio-resin has a softening point of from about 100°C to about 150°C. Most preferably, the bio-resin has a softening point of from about 130°C to about 135°C. The bio-resin may preferably comprise post-reacted units of at least one of: 1,4-cyclohexanedicarboxylic acid; C of one or more of oleic acid, linoleic acid and linolenic acid; 18 Fatty acid dimerization products; trimethylolpropane; and isosorbide....

Embodiment 1

[0179] The first premix formulation contained: 100 parts by weight (88% by weight) bioresin HRJ16062-C (obtained from Advanced Image Resources of Alpharetta, Georgia), 8 parts by weight colorant in the form of Mogul-L carbon black (CB) ( obtained from Cabot Corporation of Boston, Massachusetts), 2.5 parts by weight of wax in the form of WE3 (an ester type wax, obtained from Japan NOF Corporation), and 1.5 parts by weight of a charge control agent (CCA) in the form of E81 (a salicylic acid, obtained from Japan Orient Chemical Industries, Co., Ltd.), wherein the weight percent is based on the total weight of bioresin, colorant, wax and charge control agent. The resin component contained 100 parts bioresin and 0 parts secondary resin.

Embodiment 2

[0181] The second premix formulation contained: 100 parts by weight (87.5% by weight) bioresin HRJ16062-C (obtained from Advanced Image Resources of Alpharetta, Georgia), 8 parts by weight colorant in the form of Mogul-L carbon black (CB) ( available from Cabot Corporation of Boston, Massachusetts), 2.5 parts by weight of wax in the form of WE3 (an ester-type wax, available from Japan NOF Corporation), and 2.0 parts by weight of a charge control agent (CCA) in the form of DLN-32CW (a Azo-type dyes, obtained from Hubei Dinglong Chemical Co., Ltd., Wuhan, China, wherein the weight percent is based on the total weight of bioresin, colorant, wax and charge control agent. The resin component contained 100 parts bioresin and 0 parts secondary resin.
