Under the scope, it can be changed to any method.

<Polycarbonate resin (A)>

The polycarbonate resin (A) used in the present invention is a polycarbonate resin (A) containing a polycarbonate resin as a main component. Here, the term "mainly composed of polycarbonate resin" means that the content of polycarbonate resin exceeds 50% by mass. The polycarbonate resin (A) preferably contains 75% by mass or more of polycarbonate resin, and more preferably contains 90% by mass or more of polycarbonate resin. In essence, it is composed of polycarbonate resin. The one is better. The polycarbonate resin (A) contains a carbonate bond in the molecular main chain. That is, if it contains -[OR-OCO]- unit (in the formula, R contains an aliphatic group, an aromatic group, or both aliphatic and aromatic groups, and is shown to further have a linear structure or a component There are no particular limitations on the branch structure, and it is particularly preferable to use a polycarbonate containing a structural unit of the following formula [1]. By using such polycarbonate, a resin laminate having excellent impact resistance can be obtained.

Specifically, for the polycarbonate resin (A), aromatic polycarbonate resins (for example, Upiron S-2000, Upiron S-1000, Upiron E-2000 commercially available from Mitsubishi Engineering-Plastics Co., Ltd.) can be used. )Wait.

In recent years, the front panel has also increased the need for bending processing. Therefore, the polycarbonate resin (A) is based on the following The monovalent phenol represented by the formula [2] is preferably synthesized as a terminal stopper.

(式中，R₁表示碳數8~36之烷基或碳數8~36之烯基， R₂~R₅各自表示氫、鹵素、或可具有取代基之碳數1~20之烷基或碳數6~12之芳基，取代基為鹵素、碳數1~20之烷基或碳數6~12之芳基。)

(In the formula, R ₁ represents an alkyl group with 8 to 36 carbons or an alkenyl group with 8 to 36 carbons, and R ₂ to R ₅ each represent hydrogen, halogen, or optionally substituted alkyl with 1 to 20 carbons Or an aryl group with 6 to 12 carbons, and the substituent is halogen, an alkyl group with 1 to 20 carbons or an aryl group with 6 to 12 carbons.)

The monovalent phenol of general formula [2] is more preferably the monovalent phenol represented by the following formula [3].

(式中，R₁表示碳數8~36之烷基或碳數8~36之烯基。)

(In the formula, R ₁ represents an alkyl group with 8 to 36 carbons or an alkenyl group with 8 to 36 carbons.)

_{The carbon number system of R 1} in general formula [2] or general formula [3] is more preferably within a specific numerical range. Specifically, the _{upper limit of the carbon number of R 1} is 22 more preferably, and 18 is particularly preferable. In addition, with regard to the lower limit of the carbon number of _{R 1, 12 is more preferable.}

Among the monovalent phenols (terminal stoppers) represented by the general formula [2] or general formula [3], a combination of cetyl p-hydroxybenzoate and 2-hexadecyl p-hydroxybenzoate is used. Either or both are particularly preferred as end stop agents.

Regarding R ₁ , for example, when monovalent phenol (terminal stopper) having an alkyl group with 16 carbon atoms is used, the glass transition temperature, melt fluidity, formability, sink resistance, monovalent phenol in the production of polycarbonate resin It has excellent solvent solubility and is particularly good when it is used as a terminal stopper for the polycarbonate resin used in the present invention.

_{On the other hand, if the carbon number of R 1} in general formula [2] or general formula [3] increases too much, the solubility of monovalent phenol (terminal stopper) in organic solvents tends to decrease, and polycarbonate resin Productivity at the time of manufacturing will decrease.

As an example, _{if the carbon number of R 1} is 36 or less, the current production of polycarbonate resin will have high productivity and good economic efficiency. If the carbon number of R ₁ is 22 or less, monovalent phenol is particularly excellent in solubility in organic solvents, and the current production of polycarbonate resins can lead to very high productivity and improved economic efficiency.

_{If the carbon number of R 1} in the general formula [2] or general formula [3] is too small, the glass transition temperature of the polycarbonate resin cannot become a very low value, and the thermoformability may be reduced.

In addition, in the polycarbonate resin (A), a polyester carbonate-based resin having an ester bond and a carbonate bond in the polymer skeleton may also be used.

In the present invention, the weight average molecular weight of the polycarbonate resin (A) affects the impact resistance and molding conditions of the resin laminate. That is, when the weight average molecular weight is too small, the impact resistance of the resin laminate will decrease, which is not good. When the weight average molecular weight is too high, an excessive heat source may be necessary when laminating the resin containing the polycarbonate resin (A), which is not preferable. According to the molding method, since a higher temperature is required, the polycarbonate resin (A) will be exposed to high temperatures, which will adversely affect its thermal stability. The weight average molecular weight of the polycarbonate resin (A) is preferably 15,000 to 75,000, more preferably 20,000 to 70,000. More preferably, it is 25,000~65,000.

<Method for measuring the weight average molecular weight of polycarbonate resin (A)>

The weight average molecular weight of the polycarbonate resin (A) can be measured based on the description of paragraphs 0061 to 0064 of JP 2007-179018 A. The measurement method is detailed below.

After using polystyrene (PS) as a standard polymer for measurement, the general molecular weight calibration method is used to determine the dissolution time and polycarbonate The relationship between the molecular weight of the ester (PC) is used as the calibration curve. In addition, the dissolution curve (chromatogram) of PC and the calibration curve were measured under the same conditions, and each average molecular weight was determined from the peak area (number of molecules) between the dissolution time (molecular weight) and the dissolution time. If the number of molecules of the molecular weight Mi is Ni, the weight average molecular weight is as follows. In addition, the following formula is used for the conversion formula.
