Provided is an adhesive composition comprising a modified polyolefin and an epoxy resin, the composition having excellent pot life, and excellent adhesion to both a metal substrate and a polyolefin resin substrate. The adhesive composition comprises a modified polyolefin (A), a glycidyl amine-type epoxy resin (B1), a glycidyl ether-type epoxy resin (B2), and an organic solvent (C); wherein the modified polyolefin (A) is (A1) or (A2) below:

Polyolefin-based adhesive composition

Provided is a resin composition for an adhesive comprising a polyurethane resin containing a carboxyl group, having specific range of an acid value having specific range of a number average molecular weight and having specific range of a glass transition temperature a polyester resin having specific range of a number average molecular weight and having specific range of a glass transition temperature; an epoxy resin containing a nitrogen atom; and an epoxy resin having a dicyclopentadiene skeleton, in which a content rate of the polyurethane resin to a sum of the polyurethane resin and the polyester resin is 70 to 95 percent by mass, a content rate of the total epoxy resin contained in the resin composition to the sum of the polyurethane resin and the polyester resin is 5 to 30 percent by mass.

Resin composition for adhesive, adhesive containing resin composition for adhesive, adhesive sheet containing resin composition for adhesive, and printed wiring board including adhesive or adhesive sheet as adhesive layer

A portion of light emitted from a laser source () for detecting a displacement of a cantilever () is extracted by a half mirror () and guided onto a photodetector () having a light-receiving surface divided into four sections. When the direction of the emitted light is inclined due to a change in the ambient temperature or other factors, the light spot formed on the light-receiving surface of the photodetector () moves. Accordingly, the amount and direction of the inclination of the emission direction can be recognized from the amount and direction of the movement of the light spot. A drive amount calculator () calculates a drive amount according to the amount and direction of the inclination, and operates an actuator () to rotate the laser source () around each of the Y and Z axes. This operation compensates for the inclination of the direction of the emitted light and thereby prevents the inclination from being falsely recognized as an irregularity on the sample surface.

Scanning probe microscope

This disclosure relates to a polyamideimide resin containing a structure represented by formula (1): 

Polyamideimide resin, as well as a colorless and transparent flexible metal-clad laminate and circuit board obtained therefrom

A scanning probe microscope scans the surface of a sample while making a cantilever to which an exploratory needle is attached oscillate near its resonance point, and collects information on the surface of the sample based on the change of oscillation due to the interaction between the surface of the sample and the exploratory needle. The scanning probe microscope includes a plurality of oscillators attached to the cantilever for oscillating the cantilever, and an oscillator drive device connected to the oscillators for selectively applying an alternating voltage for excitation to the plurality of oscillators.
