The present invention discloses an energy curable, single phase, aqueous composition comprising water, an ethylenically unsaturated oligomer, and an ethylenically unsaturated resin containing neutralized acidic or basic functional groups. Advantageously, in certain embodiments, the compositions contain greater than 25 wt. % water at less than 60 wt. % resin in the total composition.

Single phase water based energy curable compositions and method of preparing coatings and printing inks

Single phase, water based, energy curable compositions and a method of preparing coatings and printing inks from same.

Single phase water based energy curable polymers and method of preparing coatings and printing inks

The present invention provides a method for producing a low-odor, printed packaging material and the printed packaging material produced thereby. The printed packaging material of the present invention is especially suitable for packaging of substances, such as food, drugs and tobacco, which require low odor from printing inks. In this process, the printed ink is activated by exposure to actinic radiation, such as UV light, before an actinic-radiation curable coating is applied thereto. The exposure of the printed ink to UV light reduces residual solvent content and odor of the packaging material and improves the friction resistance and gloss of the printed images. Furthermore, the exposure of the printed packaging material to UV light provides an additional benefit of reducing microbial count, thereby extending a shelf-life of the packaged substance, such as food and drugs.

Method of manufacturing of low-odor packaging materials

An aqueous polymer dispersion comprising a polymer substantially free of cationic polymerizable groups and a cationic photoinitiator, wherein the polymer is capable of being precipitated by an acid or base generating photoinitiator upon exposure to radiation and is optionally an energy curable polymer.

Photoneutralization of pH sensitive aqueous polymeric dispersions and methods for using same

Polymers comprising a polymer backbone having pendant or terminal betadiketone groups which contain at least one trifluoromethyl group. The betadiketone groups may be selected from trifluorocetoacetate groups (general formula I); ##STR1## hexafluoroacetylacetone groups (general formula II); ##STR2## or trifluoro-2,4-pentanedione groups (general formula III); ##STR3## where  indicates the polymer backbone, R is an alkyl, substituted alkyl, aryl or substituted aryl group and R.sup.1 is hydrogen, alkyl or substituted alkyl. Neither the R group nor the R.sup.1 group should contain any group which is sufficiently basic to initiate cyanoacrylate polymerization or any group sufficiently acidic to interfere with chain transfer.

Polymers comprising betadiketone groups and polymerizable compositions

Cationically polymerizable styryloxy resins having urethane linkages, represented by the formula III ##STR1## wherein R.sup.1 and R.sup.2 are H, or one of R.sup.1 and R.sup.2 is H and the other is methyl;

Polymerizable styryloxy resins and compositions thereof

Polyfunctional cationically polymerizable styryloxy compound of the formula ##STR1## where R.sup.1 and R.sup.2 are H, or one of R.sup.1 and R.sup.2 are H and the other is methyl; R.sup.3 and R.sup.4 are H, lower alkyl, or alkoxy if R.sup.2 is not methyl; R.sup.5 is a divalent hydrocarbon radical; G is any multivalent organic or inorganic radical free of amino, aliphatic hydroxyl, aliphatic thiol or other groups which interfere with cationic polymerization; and n is an integer of two or more.
