摘要:
A three-component mixing apparatus and a three-component mixing adhesive kit, which allow anyone to easily and uniformly mix three kinds of drugs in mixing a three-component adhesive used in, e.g., surgical procedure (or treatment) or dental procedure (or treatment), includes a syringe filled with a first drug; a plunger; and an infusion-needle connector having a connecting part for a second drug container and a connecting part for a third drug container and a confluent path formed on a base end part. The first drug, the second drug and the third drug are mixed in the syringe by removably attaching the infusion-needle connector to a discharge opening of the syringe, the second drug container to its connecting part and the third drug container to its connecting part and then pulling the plunger inserted into the syringe to introduce the second drug and the third drug into the syringe.

A binder resin for toners which is excellent in fixability and non-offset properties even when used in a high-speed copier and is excellent also in suitability for pulverization, long-lasting developing properties, etc.; and a toner for electrophotography. The binder resin for toners comprises a resin which is obtained by mixing a vinyl polymer with a crosslinked resin obtained by reacting a vinyl polymer having a specific molecular weight and a specific functional-group content with a crosslinking agent and which has a specific gel content. A toner made with the binder resin is excellent in performances including fixability even when used in a high-speed copier. Even when continuously used for long in a copier, the toner gives electrophotographic prints with satisfactory reproduction.
摘要:
A binder resin for a toner which comprises at least three types of vinyl polymers each having a molecular weight, a content of a functional group or the like different from one another and a cross-linking agent preferably having a vinyl polymer structure, and has a specific gel content. The binder resin for a toner and a toner using the resin are excellent in the fixability at a low temperature and also are excellent in the resistance to offsetting phenomenon and blocking, pulverizability, durability in development, and the like, and thus can be suitably used as those for a high speed copier.
摘要:
Disclosed is a binder resin for toner which contains a styrene acrylic resin having a gel component and a small amount of volatile component. Also disclosed are a method for producing such a binder resin and a toner employing such a binder resin. A binder resin (A) for toner contains a styrene acrylic resin having a structure derived from a carboxyl group and a structure derived from a glycidyl group wherein the content (AIS) of the gel component is 1 mass% ≤ AIS ≤ 50 mass% and the content (AVO) of the volatile component in the resin is AVO ≤ 200 ppm.
