    摘要： The present invention relates to a process for preparing a polyester (meth)acrylate resin (I), said process comprising the steps of: (a) Reacting a thermoplastic polyester with (a1) at least one polyhydric alcohol and, optionally, with (a2) at least one triglyceride, wherein the molar ratio of triglyceride to thermoplastic polyester is between 0 and 0.3, and the molar ratio of polyhydric alcohol to thermoplastic polyester is at most 1.9 to obtain a depolymerization product A that has a hydroxyl number within the range of from 200 to 800 mg KOH/g; (b) Reacting the depolymerization product A with (b1) at least one fatty acid and/or (b2) at least one polybasic carboxylic acid and, optionally, with (b3) at least one polyhydric alcohol to provide a polyester polyol B; (c) Reacting the polyester polyol B with (c) at least one (meth)acrylating compound to provide a (meth)acrylated compound (I), wherein the weight ratio of fatty acid (b1) to the depolymerization product A is between 0 and 0.6, wherein the weight ratio of polybasic carboxylic acid (b2) to the depolymerization product A is less than 0.3, wherein the weight ratio of (meth)acrylating compounds (c) to the depolymerization product A is between 0.1 and 0.8, and wherein the (meth)acrylated compound (I) that is obtained has a number average molecular weight (Mn) of between 500 and 5,000 Dalton. Typically PET is used as starting material. Typically compounds (I) of the invention have a PET content of at least 15 wt %, preferably at least 25 wt %. The present invention also relates to (meth)acrylated compounds (I) thus obtained and to coating compositions and inks based upon these materials. Materials of the invention allow the use of a high amount of PET waste. Inks and coatings prepared from these materials exhibit an excellent pigment wetting and/or ink-water balance.

    摘要： The present invention relates to stabilizers for thiol-ene compositions and to radiation curable thiol-ene compositions based thereon. Such radiation curable compositions can advantageously be used in inks, overprint varnishes, coatings, adhesives, for the making of 3D objects and for the making of solder resist and gel nails. Provided in particular is an inhibitor system (I) for thiol-ene compositions based on —at least one inhibitor compound (i) having a % DPPH radical scavenging activity of at least 90%, the inhibitor compound (i) being selected from substituted benzene compounds or substituted naphthalene compounds containing at least two substituents selected from the group consisting of hydroxyl groups and C1-C3 alkoxy groups bonded directly to the benzene or the naphthalene ring, —at least one acidic compound (ii) having a pKa between 1 and 3, and —at least one compound (iii) selected from the group consisting of phosphites and phosphonites, with the proviso that if the inhibitor compound (i) is a substituted benzene that it contains at least two hydroxyl groups bonded directly to the benzene ring. Also provided is an inhibitor system (II) for thiol-ene compositions based on that is based on —at least one inhibitor compound (i) having a % DPPH radical scavenging activity of at least 90%, the inhibitor compound (i) being selected from substituted benzene compounds or substituted naphthalene compounds containing at least two substituents selected from the group consisting of hydroxyl groups and C1-C3 alkoxy groups bonded directly to the benzene or the naphthalene ring, —at least one compound (iv) selected from the group consisting of spirophosphites, and —optionally, at least one acidic compound (ii) having a pKa between 1 and 3, and with the proviso that if the inhibitor compound (i) is a substituted benzene that it contains at least two hydroxyl groups bonded directly to the benzene ring.

    摘要： The present invention relates to a radiation curable aqueous composition comprising at least one ethylenically unsaturated polymer (1) which is the reaction product of—a water-dispersible (meth)acrylic polymer A containing pendant hydroxyl or isocyanate groups, and containing pendant groups capable to render the polymer dispersible in aqueous medium either directly or after reaction with a neutralizing agent; —at least one ethylenically unsaturated compound B which can be radically polymerized under irradiation and which attaches to the (meth)acrylic polymer A by an urethane linkage; —and, optionally, at least one neutralizing agent C. The present invention further relates to the making and use of such radiation curable aqueous compositions.
