    摘要： A leather obtained by a (1) pre-treatment before tanning, (2) tanning process where glutaraldehyde is used as a tanning agent, (3) process where a re-tanning agent is used which is constituted by synthetic tannin, resin and aluminum, of which the synthetic tannin is constituted by (a) condensation product of aromatic sulfonic acid with formaldehyde or mixture of aromatic sulfonic acid and condensation product of aromatic sulfonic acid with formaldehyde, (b) methylene cyclic polymer of aromatic sulfonic acid with hydroxy aromatic compound or mixture of aromatic sulfonic acid and methylene cyclic polymer of aromatic sulfonic acid with hydroxy aromatic compound and (c) glyoxal, while the resin is constituted by (a) acrylic acid, methacrylic acid, acrylic acid ester or methacrylic acid ester polymer(s) and mixture thereof, and copolymer(s) thereof or mixture thereof and (b) polycondensation product of melamine with formaldehyde, wherein the re-tanning agent having the aforementioned composition is used to perform re-tanning, followed by dyeing as well as fatliquoring treatment using a fatliquoring agent constituted by (a) synthetic oil and natural oil and (b) mixture of synthetic oil and natural constituent, and (4) post-treatment after re-tanning; wherein said leather is characterized in that it is flexible and has unique elasticity and softness beyond what is presented by the material hide and has restorability that prevents the leather from stretching more than it should, and also in that its conditions include a BLC stiffness/softness of 4.42 mm or more but 4.90 mm or less and maximum set ratio of 10.7 or more but 13.9 or less.

    摘要： The invention relates to a tanning agent that is produced by reacting at least one aldehyde of general formula (I) with at least another identical or different aldehyde of formula (I), wherein the variables are defined as follows: Z is a single chemical bond, an optionally substituted C1-C12-alkyl, an optionally substituted C5-C12-cycloalkyl or an optionally substituted C6-C14-aryl, wherein the reaction is carried out in the presence of an acid catalyst and optionally in the presence of at least another carbonyl compound of formula (II), R to R represent, independent of one another, hydrogen, optionally substituted C1-C12-alkyl, optionally substituted C3-C12-cycloalkyl, optionally substituted C7-C13-aralkyl or optionally substituted C6-C14-aryl, provided that at least another aldehyde of formula (I) in which the radical of Z contains alpha hydrogen atoms or at least another carbonyl compound of formula (I) is present when Z is a single chemical bond or a radical without any hydrogen atoms. The invention also relates to a method for the production of said tanning agent, to the utilization thereof as curing agent, particularly for pretannage, tannage or retannage of animal skins using the inventive tanning agents. The invention further relates to a powder active agent containing one or more of said inventive tanning agents, to a method for the production of said powder active agents and to the use thereof as curing agent and to leather produced using the inventive tanning agents or the inventive method.
