摘要:
An agent for dissolving dental calculus and/or dental caries, which comprises one or more kinds of substances selected from the group consisting of inositol phosphoric acid esters (e.g., phytic acid), polyphenols (e.g., Perilla frutescen var. crispa polyphenols), phosphoric acids, edetic acid salts, tartaric acid, malic acid, citric acid, and glycolic acid as an active ingredient. Dental calculus and/or dental caries can be conveniently dissolved in a short period of time.
摘要:
The present invention relates to an adhesive film with which a flexible metal-clad laminate is obtained with suppressed dimensional changes occurred when produced by a laminating method; and a flexible metal-clad laminate comprising the adhesive film and a metal foil bonded thereto. The adhesive film comprises a polyimide film and, formed on at least one side thereof, an adhesive layer comprising a thermoplastic polyimide and has coefficients of linear expansion satisfying the relationship 1.0>(coefficient of linear expansion in the MD direction)/(coefficient of linear expansion in the TD direction)>0.1. This adhesive film may be one produced continuously and further satisfying the relationship 1.70>(elastic modulus in the MD direction)/(elastic modulus in the TD direction)>1.05 when the adhesive film has an MD modulus of 5 GPa or higher throughout the whole width thereof. That adhesive film may be one produced continuously and further satisfying the relationship 2.00>(elastic modulus in the MD direction)/(elastic modulus in the TD direction)>1.10 when the adhesive film has an MD modulus less than 5 GPa throughout the whole thereof.

The present invention relates to a method for continuously producing a synthetic resin film that has stable physical properties across the full width and that is useful for an electronic field. In particular, the present invention relates to a method for continuously producing a synthetic resin film having molecular orientation controlled in the MD direction. That is, the present invention provides a method for continuously producing a synthetic resin film, the method including (A) a step of continuously flow-casting and applying a composition containing a polymer and an organic solvent onto a support to form a gel film; (B) a step of stripping the gel film from the support and fixing both ends of the gel film; and (C) a step of transporting the film with both ends being fixed in a oven, wherein in at least part of step (C), the film is fixed so that substantially no tension is applied in the width direction of the film (TD direction).

It is an object of the present invention to provide a stable process for continuously producing a synthetic resin film oriented in the machine direction across the full width. The present invention provides a process for producing a synthetic resin film including step (A) of casting and applying a composition containing a polymer and an organic solvent onto a support to form a gel film; step (B) of stripping the gel film and heating the gel film with both ends being fixed; and step (C) of heating the film with both ends being released after step (B), wherein the thickness b of the film produced in step (B) and the thickness c of the film produced in step (C) satisfy the relationship: b>c.
摘要:
A polyimide film according to the present invention satisfies Condition (1) in which a tear propagation resistance variation CH is not more than 1.0 g, and/or Condition (2) in which a swelling coefficient CR after being dipped in an alkaline solution is not more than 20.0. By satisfying these conditions, workability of the polyimide film can be improved and working defects can be effectively prevented, thereby improving productivity of each step.

摘要:
A fluoro-carbon resinous laminate has a crack-resistant surface on a fluoro-carbon resinous layer thereof produced by coating a single surface or both surfaces of a plastic film with a single layer of a fluoro-carbon resinous dispersion, and a method of producing the laminate. To produce the fluoro-carbon resinous laminate, which is a minimum of 10 .mu.m in thickness, a single surface or both surfaces of a plastic film are coating with a single layer of concentration-adjusted fluoro-carbon resinous dispersion and then dried, followed by curing the resinous dispersion in a thermal treating furnace with heated atmospheric air or by adding organic solvent to the resinous dispersion, the enabling production of a fluoro-carbon resinous laminate having a surface appearance in which cracks cannot visually be identified.
