The invention provides a high-toughness photosensitive resin for 3D printing and a preparation method thereof. The photosensitive resin comprises a photosensitive resin (maleable photosensitive resin and rigid photosensitive resin), an active diluent, a light initiator and an additive. The method first synthesizes the toughness photosensitive resin (maleable polyurethane acrylate and epoxy modified polyurethane), and then the maleable photosensitive resin is mixed with the rigid photosensitive resin, active diluent, light initiator and additive. The maleable photosensitive resin is prepared from a polymer soft segment, which is a mixture of one or more selected from of polypropyleneoxide glycol ether, PTMG, hydroxyl-terminated polybutadiene, hydroxyl-terminated styrene butadiene rubber, hydroxyl-terminated butadiene acrylonitrile rubber and hydroxyl-terminated polysiloxane, and a polymer hard segment of toluene diisocyanate or isophorone diisocyanate, through hydroxyethyl acrylate or epoxypropanol termination. The photosensitive resin is applicable to DLP or SLA type 3D printers for modification of the existing 3D printing photosensitive resin, has excellent bending strength, and can directly print out elastic models.

The invention relates to the formulation and application of water based predominantly pH neutral microemulsions and microemulsion forming surfactant systems essentially comprising a surfactant or surfactant˜end, lactates)—esters) of lactic acid—and water/brine and optionally solvent. Uniquely the formulations are acid and caustic free and also do not make use of alcohol, glycol and glycol ether components in the systems as co surfactant, co-solvent or mutual solvent. In particular the invention relates to the methods and the application of this microemulsion technology for use in industrial hard surface cleaning applications especially the inks and printing industries and the oil and gas industry. In addition the formulations can be used in the production of microemulsion based drilling muds (which may or may not be Oil Based Muds—OBMs) and they may be used to enhance the drill cuttings slurrification processes for re-injection purposes or for facilitated cuttings transport.

An improved via and contact hole fill composition and method for using the composition in the dual damascene production of circuits is provided. Broadly, the fill compositions include a quantity of solid components including a polymer binder and a solvent system for the solid components. The boiling point of the solvent system is less than the cross-linking temperature of the composition. Preferred solvents for use in the solvent system include those selected from the group consisting of alcohols, ethers, glycol ethers, amides, ketones, and mixtures thereof. Preferred polymer binders are those having an aliphatic backbone and a molecular weight of less than about 80,000, with polyesters being particularly preferred. In use, the fill composition is applied to the substrate surfaces forming the contact or via holes as well as to the substrate surfaces surrounding the holes, followed by heating to the composition reflow temperature so as to cause the composition to uniformly flow into and cover the hole-forming surfaces and substrate surfaces. The composition is then cured, and the remainder of the dual damascene process is carried out.
