I've thoroughly searched the records. Here's my answer:

The records do not contain any customer statement or feedback about FOIL's samples.

What the records *do* show:

• Batch 30 (alias LBN-23) is the only batch with a customer link: the material entry reads "Sun Surfol R-1400- ( HV-36.8/ MW-1500) ( 3 kg sample to customer) R-83" — a 3 kg sample was sent to the customer, but no response, comment, complaint, or test verdict from that customer is recorded [28112025 9076 Expt Table 2025.xls, sheet 9076_Experiments, batch block '30', csv rows 4-8].

• The "not ok" application test reports (batches 63, 64, 65, 66, 68, 69, 70, and SAW 10020626) are internal FOIL lab tests comparing S 9076 against the BYK 9076 reference standard (or Finalux 108) in ink-base systems. Their verdicts — "Not OK (Gloss and Re-solubility inferior)" or "Not OK (Gloss and Colour strength inferior)" — are FOIL's own lab conclusions, not customer statements. The only people named are FOIL scientists (e.g., Mr. Mohan Yadav, Dr. Sachin Jagtap).

• The Alibaba.com BYK-9076 listing mentions "satisfied customer base" and a "Very satisfied" review, but that is vendor marketing for BYK's own product, not feedback on FOIL's samples.

Gap: There is no document in this data drop recording what the customer said after receiving the Batch 30 (or any other) sample. No email, no complaint, no trial report, no customer comment exists in the records.
