Definitions

• This invention relates to mordants for ink-jet receptors and the like and more particularly, it relates to various types of novel mordants based upon a poly(alkylene oxide) backbone.
• Mordants well-known in the photographic art, generally comprise materials containing quaternary ammonium groups as disclosed in U.S. Pat.
• Quaternary phosphonium groups have also been incorporated with certain polymer backbones to obtain different classes of mordants such as those disclosed in U.S. Pat. Nos. 3,547,649; 4,820,608; and 4,855,211; and
• the basic polymeric mordants useful to mordant a dye in a hydrophilic colloidal layer between a base and a photographic emulsion layer disclosed in
• R is hydrogen or a methyl group
• A is a -COO- or a -COO- alkylene group, e.g., -COOCH 2 -, -COOCH 2 CH 2 -, -COOCHOHCH 2 -
• R 2 is a hydrogen or a lower alkyl group having from 1-4 carbon atoms
• X ⁇ is an anion, e.g. , acetate, oxalate, sulfate, chloride, or bromide.
• Mordant I can comprise units derived from vinylic monomers, for example, acrylates, acrylamides, vinyl acetates, styrenes, vinyl ethers, vinyl ketones, vinyl alcohols, unsaturated chlorides, and nitriles with the proviso that such copolymerizable units be in a quantity of 10-20% by weight. Similar mordants with the exclusion of A in I are also disclosed in GB Patent No. 850,281.
• U.S. Pat. No. 5,354,813 discloses several classes of polymeric mordants having a pendent heterocyclic aromatic moiety, e.g. , a pyridyl or an imidazolyl group, as represented by the fomula U below:
• X " represents an anion and n represents an integer of 2 or greater.
• Mordants prepared by polymerizing or copolymerizing vinyl pyridine or N-alkyl pyridinium salts are also known in the art (see, for example, Italian Patent No. 931 ,270).
• Non-diffusive mordants based on poly(N-vinylimidazole) of the type in are known in the art (see U.S. Patent No. 4,500,631) and have been used in certain radiographic image-forming processes wherein the mordants were coupled with water-soluble dyes. Mordants of the type in as well as IV are also disclosed in Japanese Publn. No. 63-307979.
• mordants I, p-MePhSO 3
• Other types of mordants for dyes are also known in the imaging arts.
• U.S. Pat. No. 3,429,839 discloses mordants having pendant groups V, such as the mordant of formula VI :
• R,, R 2 , and R 3 are alkyl, aryl, or aralkyl groups, or any two of R, , R 2 , or R 3 are part of a 5- or 6-membered heterocyclic ring and X " is an anion, usually an anion of a mineral acid or a carboxylic acid having from 2 to 20 carbon atoms.
• R 1 , R , and R are alkyl, aryl, or aralkyl groups or any two of R] , R 2 , or R 3 are part of a 5- or 6-membered heterocyclic ring and X " is an anion.
• R 1 is an alkyl group having 1 to 6 carbon atoms, preferably 1 to 2 carbon atoms and R 2 is an alkyl, aryl, aralkyl, or alkaryl group having up to 10 carbon atoms inclusive; preferably alkyl having up to 6 carbon atoms inclusive or phenyl; 1 and n are integers of 2 or greater, preferably 2-3, most preferably 3; m is an integer of 5 or greater, preferably 30-50, most preferably 40; and Q represents — (CH 2 ) y — wherein y is 1-20, preferably 3- 4.
• X " is independently an anion, preferably CH 3 SO 3 _ , Br _ , NO 3 ⁇ , Cl ⁇ ,
• alkyl group is intended to include not only pure open-chain and cyclic saturated hydrocarbon alkyl substituents, such as methyl, ethyl, propyl, t-butyl, cyclohexyl, adamantyl, octadecyl, and the like, but also alkyl substituents bearing further substituents known in the art, such as hydroxyl, alkoxy, vinyl, phenyl, halogen atoms (F, Cl, Br, and I), cyano, nitro, amino, carboxyl, etc.
• alkyl moiety is limited to the inclusion of only pure open-chain and cyclic saturated hydrocarbon alkyl substituents, such as methyl, ethyl, propyl, t-butyl, cyclohexyl, adamantyl, octadecyl, and the like.
• the Jeffamine primary amine mate ⁇ als used in the present invention are low average molecular weight materials and are commercially available from Texaco Chemical Co.
• Two different types of Jeffamine materials are used in the present invention: Jeffamine ED-2001 [poly(propylene glycol-b- ethylene glycol-b-propylene glycol)bis(2-aminopropyl ether], weight average MW 2,000 (XIa. and Jeffamine” T-5000 [Glycerol tris(poly(propylene glycol), amine-terminated)ether], weight average MW 5,000, (Xlb).
• Example 1 To a solution of 5g Jeffamine * ED-2001 (XIa) in 20g methanol was added a solution of the chloroacetone hydrazone (2.2 molar equiv.) of aminoguanidinium chloride in 10 mL methanol. The solution was heated to about 45°C for 10-15 minutes. Mordant Xlla (where X " and Y " are Cl-) was precipitated from ether as a semi-solid and dried in vacuum.
• Example 1(a) The reaction in Example 1(a) was repeated using chloromethyl triphenylphosphonium bromide in place of the hydrazone to obtain the mordant X ⁇ I(b) wherein Q is -CH 2 - and Y " is Cl " .
• Example 2 The reaction in Example 2(a) was repeated using bromopropyl triphenylphosphonium bromide in place of chloromethyl triphenylphosphonium bromide to obtain the mordant XIKb, where Q is - CH 2 CH 2 CH 2 - and Y " is Br " .
• Example 3 To a solution of 5g of Jeffamine ® T-5000 (Xlb. in 20g methanol was added a solution of the chloroacetone hydrazone (3.3 molar equiv.) of aminoguanidinium chloride in 10 L methanol. The solution was heated to about 45-50 °C for 15 minutes to obtain the mordant XIII.
