A powder-liquid dental curable material kit composed of (A) a liquid material and (B) a powder material, wherein the liquid material (A) contains (a1) a radically polymerizable (meth)acrylic monomer, (a2) an organic halogen compound and (a3) a radical chain transfer agent; the powder material (B) contains (b1) non-crosslinked resin particles, (b2) a pyrimidinetrione compound and (b3) an organic metal compound; and (Z) a peroxide is blended in at least one of the liquid material (A) and the powder material (B). This curable material kit is capable of reducing the heat generation during the curing of a curable material which is a mixture of the liquid material (A) and the powder material (B) and is not susceptible to the excessive prolongation of the curing time even when the curable material is cured by a brush-on technique, thereby ensuring an appropriate curing time for both of a brush-on technique and a kneading technique.

The present application describes a process for removing toxic compounds, namely carbon dioxide, present in gas streams in anesthesia circuits, using membrane contactors. The present process allows for the recirculation of anesthesia gases, CO2 free, to the anesthetized subject, as well as the recirculation of the receiving absorber liquid phase, from which the CO2 is removed.
The present application also describes the use of this procedure in the field of medicine, namely its in-situ use during medical interventions, in which the subject is anesthetized.
The present invention provides a powder-liquid type denture base liner comprising: a powder material including (A) uncrosslinked resin particles, (B) an organic peroxide, (C) a pyrimidine trione derivative, and (D) an organic metal compound; and a liquid material including (E) a radical polymerizable monomer and (F) an aromatic amine compound, wherein the powder-liquid denture base liner is characterized in that the (C) pyrimidine trione derivative is 0.0002-1.0 mass parts per 100 mass parts of (E) radical polymerizable monomer.
An object of the present invention is to provide a dental composition that can exhibit sufficient curability even in a state where moisture is excessive as in the oral environment.
The dental composition of the present invention contains component (a): monomer containing (meth)acrylamide group represented by formula (1):
(In formula, R represents a hydrogen atom or a methyl group and Rs may be the same or different from each other. R2 is an alkyl group having 2 to 6 carbon atoms and R2s may be the same or different from each other.)
