摘要:
The invention relates to pigment preparations containing as principal ingredients: A) at least one organic or inorganic pigment in the form of fine particles, B) a dispersing agent on the basis of arylsulfonic acid-formaldehyde condensation products or of oxalkylated phenols, C) an alkali-soluble acrylic resin, D) an inorganic or organic base and E) water.
摘要:
The invention relates to colorant preparations containing the following main constituents: A) at least one dispersed (A1) or dissolved (A2) colorant; B) if a colorant corresponding to (A1) is used, a dispersing agent; C) a low-molecular polytetrahydrofurane (C1), optionally mixed with one or more difficult-to-evaporate, water-soluble or water-miscible organic solvents (C2); and D) water.
摘要:
Disclosed is a method for coloring textile substrates, which is characterized in that textile substrates (a) are pretreated with an aqueous pretreatment bath containing (A) at least one resin selected among melamine derivatives, dimethylol dihydroxy ethylene urea (DMDHEU), and DMDHEU derivatives, and (B) at least one thickener, and are then (b) printed using inkjet technology.
摘要:
An aqueous pretreatment liquor for preparing textile substrates for inkjet printing containing (A) one or several polycationic compounds, (B) one or several thickening agents, (C) optionally usual additives, (D) water. Preferred polycationic compounds (A) are polymers or copolymers of diallyldialkylammonium monomers. Preferred thickening agents are obtained from (i) polyetherdiols, (ii) diisocyanates and (iii) compounds of general formula R-OH, R-SH, R-NH2, RR'NH or R-COOH, wherein R, R' represents a hydrophobic, aliphatic or aromatic radical having at least 4 C atoms and R-OH can also be alkoxylated, in addition to other derivatives of said compounds capable of producing a urethane, thiourethane or urea bond (i), or can be obtained from polyetherdiols with (iv) compounds of general formula R-OH or R-COOH, wherein R is a hydrophobic, aliphatic or aromatic radical having at least 4 C atoms and R-OH can also be alkoxylated, in addition to other derivatives of said compounds capable of producing ether or an ester bond, and/or from compounds (ii) or (iii).
摘要:
The invention concerns dyeing formulations consisting of the following elements: a) at least a dye selected from the group comprising hardly water-soluble dyes a1) and water-soluble dyes a2), b) water, c) in the case of hardly water-soluble dyes a1), at least a dispersant and d) at least a compound of formula (I), wherein the variables are defined as follows: R1, R2 are selected independently of each other from the group consisting of hydrogen, C1-C4 alkyl, CH2-O-R3, R3 representing hydrogen or C1-C4 alkyl.
