Definitions

• This invention pertains to an inkjet ink, in particular to an aqueous inkjet ink com- prising pigment colorant and a specified latex binder.
• the ink is particularly advantageous for jetting onto textile substrates.
• a digital printing method such as inkjet printing offers a number of potential benefits over conventional screen printing methods.
• Digital printing eliminates the set up expense associated with screen preparation and can potentially enable cost effective short run production.
• Inkjet printing furthermore allows visual effects such as tonal gradients and infinite pattern repeat size that cannot be practically achieved by a screen printing process.
• inkjet printed fabrics are particularly susceptible to color removal by abrasion and thus have poor durability or crock fastness.
• US5897694 discloses inkjet ink formulations comprising, as an additive, a transi- tion metal chelate, which provides improved wash fastness.
• US5958561 discloses an ink textile combination wherein the textile is pretreated with a cross-linkable thermoplastic polymer and then imaged with an aqueous ink and cured at temperatures of 100-190°C. Improved wash fastness was obtained.

• the present invention also provides a method for ink jet printing onto a substrate, comprising the steps of:
• a preferred substrate is a textile substrate, and it is also preferred to treat the printed substrate with heat and/or pressure, and more preferably both heat and pressure (a fusing process).
• Use of the inks of the present invention for printing textile substrates can result in a crock of at least 4/dry and 3/wet according to test method AATCC 8-1996.

• aqueous vehicle refers to water or a mixture of water and at least one water-soluble organic solvent (co-solvent). Selection of a suitable mixture depends on requirements of the specific application, such as desired surface tension and viscosity, the selected colorant, drying time of the ink, and the type of substrate onto which the ink will be printed.

• 1 ,2-Alkanediols are preferably 1 ,2-C4-6 alkanediols, most preferably 1 ,2- hexanediol.
• Suitable surfactants include ethoxylated acetylene diols (e.g. Surfynols® series from Air Products), ethoxylated primary (e.g. Neodol® series from Shell) and secondary (e.g. Tergitol® series from Union Carbide) al- cohols, sulfosuccinates (e.g. Aerosol® series from Cytec), organosiiicones (e.g. Silwet® series from Witco) and fluoro surfactants (e.g. Zonyl® series from DuPont).

• the median particle size should preferably be less than 1 micron, more preferably more preferably less than 0.5 microns, and most preferably in the range of about 0.03 to 0.3 microns.
• Polymer synthesis for these latexes can be performed under emulsion polymerization conditions with standard free radical initiators, chain transfer initiators, and surfactants.

• Molecular weight (Mw) is typically in the range of 100,000 to over 1 ,000,000 g/mol. The percent conversion is also controlled to limit the gel content.
• chlorinated butadienes The reactivity of chlorinated butadienes is several times that of most vinyl or acrylic monomers, making co-polymerization with non-chlorinated monomers difficult.
• a Lewis acid complexing agent can enable copolymerization of chlorinated butadienes with most monomers such as butadiene, isoprene, dimethylbuta- diene, acrylonitrile, styrene, acrylic acid, methacrylic acid, and esters thereof.
• the latex polymers used in this invention tend to display crystallinity resulting from the polymer conformation.
• the conformation of polychloroprene for instance, is predominately 1 ,4-trans with increasing regularity inversely proportional with the polymerization temperature. While nearly 100% 1 ,4-trans polymer may be obtained by polymerization at -150°C, most commercial polychloroprenes are synthesized at 0 - 40°C and contain 90% 1 ,4-trans conformation.
• This high degree of structural regularity results in stress-induced crystallization and up to 10% crystallinity, which translates to useable strength even in the uncured resin, and high tensile strength in the cured resin.
• the degree of crystallinity and crystallization rate may also be controlled by incorporation of a small percentage of co- monomer. For the present invention, higher levels of crystallinity lead to improved abrasion resistance and better crock and wash fastness.
• the polymer latex is generally used, on a polymer solids basis, in the range of about 0.5 to about 30%, and more typically in the range of about 1 to about 20%, by weight based on the total weight of the ink.
• ingredients can be added to optimize performance.

• the ink has physical properties are adjusted to the ejecting conditions and printhead design.
