A process for producing a three-dimensional object by selectively layer-by-layer solidification of a powdery material layer at the locations corresponding to the cross-section of the object in a respective layer by exposure to electromagnetic radiation. The powdery material comprises at least one polymer which is obtainable from its melt only in substantially amorphous or completely amorphous form, or a polyblend which is obtainable from its melt only in substantially amorphous or completely amorphous form. The powdery material has a specific melting enthalpy of at least 1 J/g.

A solar reactive mulch film comprising one or more layers of heat shrink material pre-strained at a predetermined temperature and tension. Immediately cooling the pre-strained layers retains molecular deformation stresses in the material which facilitate shrinkage but not expansion on exposure to solar radiation. The mulch film adapted to be laid over longitudinal growing beds and held tautly by burying its side edges in soil. Exposure of uncovered portions of film to solar radiation causes shrinkage in one or more directions whereby in combination with the weight of the soil holding it down, maintains tautness of the mulch over a growing period. Methods of manufacture and use of the same.

Disclosed in this specification is a process for manufacturing a thermochromic contact lens. The process includes (1) selecting a photoinitiator that absorbs at a first wavelength and at least one thermochromic dye that displays substantial absorption at the first wavelength when the dye is at a first temperature and exhibits at least an 80% reduction in absorbance at the first wavelength at a second temperature, (2) maintaining the reaction mixture at the second temperature and (3) providing cure light that includes the first wavelength.

In general, the disclosure relates to methods and compositions for preparing colorants useful for preparing pigmented hydrogels. The disclosure further relates to pigmented hydrogels comprising the disclosed colorants. In some instances, the colorant is an alcohol extract of an agro-material, such as turmeric, paprika, spinach, and/or pokorny woad or the colorants comprise one or more of: a carotenoid, chlorophyll-a, chlorophyll-b, a curcumoid, or indigorubin. Alternatively, the colorant can be carbon black. The disclosure further relates to contact lenses comprising the disclosed pigmented hydrogels.
