    摘要: A base-releasing composition which suppresses release of a basic compound at room temperature and rapidly releases the basic compound under predetermined conditions. The base-releasing composition includes (A) a side-chain crystalline (meth)acrylate copolymer includes (i) repeating units each derived from an ester of a C8-C32 saturated, linear primary alcohol with acrylic acid or methacrylic acid and (ii) repeating units each derived from acrylic acid or methacrylic acid, and (B) a basic compound. The amount of basic groups in the (B) basic compound is 0.01 to 1.00 mmol per 1 g of the base-releasing composition, and at least a portion of the Component (B) is included in the Component (A). A curable resin composition includes a specific 2-methylene-1,3-dicarbonyl compound in combination with the base-releasing composition.

    摘要: A residual thermal strain distribution measurement method of measuring a residual thermal strain distribution as residual thermal deformation in a sample generated under application of a thermal load, comprises recording images of a periodic pattern present on the surface of the sample by an image recording unit at a first temperature and a sample formation temperature at which the sample is formed, generating moire fringes based on each recorded image of the periodic pattern, calculating a phase of the moire fringes for the sample at the first temperature, calculating a phase of the moire fringes for the sample at the sample formation temperature, acquiring a phase difference of the moire fringes at the sample formation temperature with respect to the first temperature, and calculating a residual thermal strain of the sample at the first temperature with respect to the sample formation temperature based on the acquired phase difference.

    摘要: There is provided a syringe filled with a resin composition which prevents a barrel cap from being detached due to temperature change during storage or during transportation, a production method thereof, and a storage method thereof. This syringe filled with the resin composition includes a syringe having a syringe barrel, a resin composition filling the syringe barrel, a plunger inserted in the syringe barrel, a barrel cap blocking an opening of the syringe barrel, and a spatial part between the plunger and the barrel cap in the syringe barrel. The pressure of the spatial part in a frozen state is 50 kPa to 92 kPa.
